In London, Eve Polastri screams in her sleep. Her husband, Niko, wakes her up and Eve tells him it was because she fell asleep on both arms. She has a headache from staying out late the night before and singing karaoke with her co-workers for her boss, Bill's, birthday. Even though it is Saturday, she has to go into work at MI5. At the office, Elena Felton explains to Eve on the way to the meeting that a Russian sex-trafficking politician was murdered in Vienna.
Eve enters the meeting late and sits down next to her boss, Bill Pargrave. Frank Haleton introduces everyone to Carolyn Martens who runs the MI6 Russia Desk. Carolyn informs them of the assassination of Victor Kedrin, a high-profile Russian politician. He was leaving a sushi restaurant near Stephansplatz with his girlfriend, Kasia Molkovska, when his femoral artery was sliced open. The girlfriend fled the scene and was picked up in Hammersmith. Eve and Bill are to provide diplomatic protection for Kasia. Eve tells Carolyn that it was a woman who assassinated Kedrin.
At MI5, Eve finds out from Elena that Kasia is still at Hammersmith station and decides to go visit her. Bill tells her that CCTV revealed it was a man who assassinated Kadrin but he hasn't actually seen the tape. Eve leaves to interview Kasia, who is on drugs and speaking incoherent Polish. The translator is unable to understand her, besides the assassin being a "plank."
Eve visits Niko at his Polish bridge club and recruits him and a Polish teenager, Dom, to listen to the recording of Kasia's babbling about the assassination. They decipher that Kasia is using slang and the assassin was tall, dark, and flat-chested, a "small-breasted psycho." Eve calls Elena at the office and requests information on Margit Polsen and any other active female assassins under the age of 45. Margit's breasts are too big for it to have been her and the other two female assassins (Katrina Voltrinski and Wendi Helmsen) are dead.
Eve is impressed with the murder of Kedrin from a tiny puncture wound and asks Niko how he might kill her. Niko says he might push her down the stairs or flatter her to death. She tells Niko she would paralyze him with saxitoxin and suffocate him in his sleep, chop him up, boil him down, put him in a blender, and then flush him down a restaurant toilet. Later, as they're going to bed, Eve questions whether or not the CCTV recording is real. Niko tells her she should have been a spy.
Eve and Bill share lunch together while Eve tries convincing Bill that Kedrin's assassin was a woman and there is a cover up with the CCTV. Eve has been compiling cases for months, including Greco's murder, that were done by a new and prolific female assassin. Bill tells her to go to the hospital to make sure Kasia is secure and then go home.
Eve takes Dom with her to the hospital and has him pretend to be Kasia's relative. While they are waiting to speak with Kasia, Eve goes to the restroom where the one stall is in use. While she is waiting, she fixes her hair. Villanelle exits a stall dressed as a nurse and watches Eve, prompting Eve to ask if she is all right. Villanelle stops on her way out of the bathroom and tells Eve to wear her hair down. While Eve is using the toilet, Bill calls to tell her that there was no CCTV and she needs to keep Kasia safe. Eve returns to the hospital room to find the nurse and the security detail are dead. She tries to stop the bleeding from Kasia's throat but Kasia dies as Dom returns with snacks.
Bill sits with Eve and tells her she did the right thing. Frank and Carolyn enter and Frank blames Eve for conducting an illegal investigation, manipulating a witness, putting a minor in danger, and failing to protect Kasia. Eve confronts Frank about the assassin being a woman and Frank fires her. Eve and Bill both call Frank a "dick-swab" and Frank fires them both.
Eve is at home watching television with Niko when her doorbell rings. Carolyn invites her to walk to the corner shop where she reveals to Eve that Villanelle has been operating for two years across ten countries. She offers to buy Eve breakfast on Thursday at 9 am at the Purple Penguin by Charing Cross.
Eve shows up at the Purple Penguin to meet with Carolyn. They discuss Eve's background: how she was born in the UK but moved to Connecticut when her parents split up and came back when her father died. Carolyn confronts Eve with a folder of documents on female assassins that they found when they were going through Eve's computer after she was fired. Eve explains that she believes there is a female assassin running around who doesn't have a specific signature but has a definite style.
Carolyn takes Eve to a decrepit building where a dingy office has been set up with all of Eve's information on the female assassin. Carolyn has set up an "unofficial-official" investigation that she wants Eve to run secretly. Kenny enters and is introduced to Eve as the person who has been gathering the evidence. Eve is allowed two more people for her team.
Eve invites Bill and Elena to come work with her. She brings them up to speed on the assassinations she believe were done by the same woman. Bill plays contrarian, asking for proof that it is the same person for all the killings and proof that it is a woman. Eve excuses herself to the bathroom and is reminded of the encounter with a nurse in the hospital bathroom before Kasia was killed. Bill has left the office and Eve chases after him as he explains he is still trying to adapt to no longer being the boss. He thinks the assassin is just a lackey and they should be going after the people controlling the assassin. Eve points out that their profile of the female assassin is the only connection they have to the people behind her. She returns to the office and asks Kenny to look up any females worldwide aged 16-45 who have medical or prison records displaying psychopathic traits. Elena leaves to meet Frank for goodbye drinks to see if she can get information on the CCTV of when Kedrin was killed.
Bill and Eve meet up with Frank and Elena at the pub. They both apologize for calling Frank a "dick-swab" for firing them before grilling him about the CCTV of Kedrin's murder. Frank laments that none of them ever invited him out for a drink after his wife died before revealing that he made up the CCTV story because he thought it was disrespectful of Bill and Eve to interfere with the investigation. Elena takes Frank out to catch a cab so he can pick up his kids.
At home, Eve lies to Niko about what she's been up to all day since being fired from MI5 before she blurts out that she's now working for MI6.
Eve describes Villanelle's features to a sketch artist while Bill looks on amused.
Niko cleans off a freshly laid egg from a chicken in their house as Eve wonders whether it is edible. Niko questions her about her new job and Eve explains it is just gathering and analyzing information.
Eve heads to the office talking to Bill on her cell phone about Carla de Mann's deadly asthma attack. She meets up with Bill carrying his baby daughter in front of their office and helps him with his "childcare emergency." Carolyn is in the office waiting for them with Elena and Kenny to let them know that there has been another assassination. Eve thinks that Carolyn is referring to Carla de Mann but Kenny tells her that it was a Chinese colonel, Zhang Wu, who has been killed. The name the assassin gave to the receptionist was "Eve Polastri". Outside, Eve paces as she begs Carolyn to keep her on the team. Carolyn asks her what she wants to do.
Eve has returned to the office and tells Bill he is going with her to Berlin. Bill tells her to take Elena instead but Eve needs Bill because he speaks German and has Berlin contacts. Bill jokes that he is going to die while Eve tells him that it is not likely that Villanelle will still be there.
Niko arrives home early as Eve struggles to get a suitcase down to begin packing for her trip. He reminds her to label her suitcase so that she does not lose another one.
Eve and Bill have arrived in Berlin and take a taxi to the "Hot Medica" building where Villanelle sits across the street watching. They are greeted by Weber, one of Bill's contacts, who takes them to the murder scene where Zhang was poisoned with carbon monoxide. Jin Yeong from the Chinese government has asked for a second opinion on the autopsy so Eve will have to contact him for a copy of the autopsy report. They leave the building and Eve asks Bill to watch their suitcases while she calls Kenny to see if he can locate Jin's whereabouts from his email address. Kenny sends her Jin's location as she notices that her suitcase has gone missing.
Bill apologizes to Eve for losing her suitcase as they scope out Jin's location. She mentions that Niko will be upset about her losing the green scarf. They approach Jin and ask him about Zhang and the second autopsy, which now says that Zhang died of a heart attack. Jin invites Eve to dinner so they can continue their discussion. After they leave their meeting with Jin, Bill warns Eve that Jin wants to have sex with her. He tells her to get something nice because he will take her out afterwards. Villanelle bumps into Bill on the street and keeps walking.
While Eve tries on outfits for her dinner, she talks on the phone to Elena, asking for intel on Jin. While she tries on a dress, Villanelle keeps a watchful distance. Back at the hotel, Niko video calls her from a dinner party at their house that she had forgotten about. Niko asks her about her new dress and she explains about the dinner with Jin. Bill knocks on the door bringing her a razor.
Eve shaves her armpits as Bill critiques her fashion sense, telling her she needs to remove her bra. They discuss Bill's wild years in Berlin and his open marriage. Bill quizzes her teasingly on whether she is attracted to women, specifically to Villanelle. Bill walks Eve to the train station and spots Villanelle watching Eve as he is leaving. He follows her and stops her from getting on the same train as Eve on the pretext of asking her about the green scarf that she is wearing - the same one that Eve had had in her suitcase. Villanelle plays it off that she got it from her mother and leaves the station with Bill following her.
Eve arrives to her dinner with Jin. He presents her with a gift and withholds information until they've had a glass of wine. Eve becomes frustrated with Jin and finally manages to pry out of him that the Chinese government might be covering up the cause of death because of "sex" but that they did not have Zhang assassinated. He has to drop the investigation but prompts Eve to keep it going.
Jin reveals to Eve that the week before, Zhang had hacked into a Chinese Intelligence agent's account and discovered that the agent had been getting paid millions. That agent is now also dead. Eve finally opens the gift Jin presented her with at the beginning of the meal and discovers that it is a 32GB memory stick. Bill leaves another message for Eve which prompts her to check her voicemail. She leaves Jin and goes to meet up with Bill.
Eve arrives at the club where Bill and Villanelle are at and explains to the bouncers that she needs to get in because she is with the British authorities and it is an emergency. Bill spots Villanelle and tries to catch up with her while Eve makes her way along the dance floor looking for him. Villanelle turns around and smiles at Bill before heading toward him. He tries to run away but is trapped in the dancing bodies and Villanelle easily catches him, stabbing him repeatedly with a short blade, before taking off again. Eve struggles to reach Bill as he bleeds out on the dance floor.
Eve and Niko attend Bill's funeral service, seated behind Bill's wife, Keiko, and their baby daughter. Frank goes up to say a few words and Eve is disgusted with his terrible speech. When Bill's daughter begins crying, Eve stands up and hurriedly leaves the service while Frank is still talking. Elena follows Eve outside and they console each other, reiterating that no one is to know the truth of how Bill died. The official story is that he was mugged at a club.
Niko offers Eve stew and wine while Eve sits forlornly on the couch. Niko confronts Eve about Bill's death and how he is worried about her. They briefly fight before Niko informs her that her suitcase has returned from Berlin.
Eve is sitting on the edge of her bed and crying. She gets her suitcase and opens it, discovering it has been repacked with new clothing with the tags still on. She finds a box of "La Villanelle" eau de parfum. The card inside reads "SORRY BABY x." Eve hastily tosses it back into the suitcase and warns Niko to stay out.
The next morning, Eve meets with Elena and Kenny to discuss the suitcase and perfume. She assigns them the task of finding out where the clothes were bought and if there is any DNA or security footage. They head to the office as Eve continues providing instructions but stops when she sees Bill's empty desk. Kenny has gone through the documents Jin Yeong gave Eve at their dinner in Berlin and there are bank statements from the Cayman Islands used to pay off the Chinese double agents that Zhang Wu uncovered. Kenny has noticed a British account number receiving three payments a year of $17,700 that terminates at St. Henry's prep school in Sussex.
Eve meets Carolyn at a butcher shop. She tells Carolyn about a work party a year ago where Frank got really drunk and emotional about not being able to afford to send his kids to St. Henry's school. Kenny tracks Frank down to a village called Bletcham in Buckinghamshire. Eve decides Elena will go with her to Bletcham to do surveillance on Frank.
As Elena drives Eve to Bletcham, Elena tells stories about how Carolyn has saved the world several times going all the way back to the '80s when she stopped an ex-KGB agent from selling plutonium. Kenny calls Eve to let her know that someone called Frank's phone from a landline at the same place his phone is at.
As Elena and Eve arrive in Bletcham, Kenny relays to them that Frank is speeding away. Eve has Elena pull over while she calls Frank. Frank has stopped his car and is hiding in his front seat. He is panicking and Eve tries to calm him down. Eve tells Frank to move toward a visible tower in the distance as she and Elena get back in the car to intercept him. Frank runs toward Eve and Elena as Villanelle shoots at him. Frank makes it to their car as Villanelle approaches, aims her gun at Eve, and shoots.
Eve is in the driver's seat of the car while Elena and Frank cower in the back seat as Villanelle approaches on foot. She fires her gun at Eve but misses. She continues shooting as Eve drives away. Eve stops the car and decides to confront Villanelle. Ignoring the protests of Elena and Frank, she gets out of the car and begins walking toward Villanelle. When Villanelle raises her gun and takes aim, Eve stops walking, placing one hand in the air, the other across her chest. Villanelle aims the gun under her own chin and Eve screams, "no!" Villanelle laughs and fires at Eve's feet instead, causing her to duck and flinch. When Eve turns back around, Villanelle is gone.
Elena and Eve take Frank to a diner and question him about the assassination attempt made by Villanelle, Nadia, and Diego. Eve instructs Frank to to leave his kids at his mother-in-law's for a few nights. Frank remembers that one of the girls was named Oksana. Eve contacts Kenny and asks him to look up the name Oksana. He tells Eve that the DNA results on her suitcase came back and Villanelle's DNA is all over it.
Eve and Elena take Frank to a safe house where Max Sanford will be looking after him. Carolyn is at the safe house and Frank starts making excuses before complaining that he is having a panic attack. Carolyn gives him five minutes to change clothes under Max's supervision. Elena brings tea to Eve and Carolyn before heading back to the office. Max tells Carolyn Frank won't come out so Carolyn goes to Frank's room and cradles him in her arms, getting him to talk. Frank reveals that "the Twelve" know everything about Frank, including his deceased wife's cancer treatments. They were willing to pay for her treatments in exchange for Frank telling them the big picture of what is going on at MI5. Frank assumed they were Russian SVR agents and was the one who told them that Eve was still investigating. Frank explains there is a pattern to Villanelle's kills and the plan is to destabilize and cause chaos.
Eve calls Kenny for an update and lets him know about the Twelve. She encourages him to give Elena a call. Back inside the safe house, Carolyn tells Eve that the police have found Diego's body but no one else. Carolyn asks after Kenny since Bill's death because Kenny's own father died a few years ago. Eve promises to keep an eye on him.
Eve sits at a bus stop and pokes at a crack in the windscreen. She stands up and slams her fist against it, shattering the window. Her phone rings and she answers Niko's call, telling him to bring Dom with him. She hurries away from the bus shelter.
The office is empty when Eve gets there. She picks up a baby blanket off Bill's desk when Kenny returns. He tells her she should still talk to Bill even though he is gone because it helps. Kenny has found prison records on a few people named Oksana and Eve stops when she sees the picture for Oksana Astonkova. Kenny tells her that she supposedly died in prison four years ago. She was imprisoned because she "chopped [a man's] knob off."
Eve arrives home and unpacks the suitcase, applying some of the perfume Villanelle made for her. She tries on a dress and a pair of shoes, admiring herself in the mirror. She kicks off the shoes and heads to the kitchen to review the files on Oksana and pour more wine. She hears a noise and calls for Niko before checking the front door. When she turns around, Villanelle stands in her hallway and tells her not to run. Eve runs upstairs, locking herself in a bathroom. Villanelle breaks open the door and Eve defends herself with a toilet wand. Villanelle easily overpowers her and tells her to stop screaming as Eve keeps screaming. She pins Eve into the bathtub and turns on the water to calm her down. She explains that she just wants to have dinner with Eve.
In the kitchen, Eve only has leftover shepherd's pie, which she microwaves for Villanelle. Villanelle helps her change out of her wet dress, complimenting her on her body. Villanelle sits down at the table as Eve gets silverware and slips a knife into her pants, which Villanelle comments on. The microwave dings and Eve brings over the shepherd's pie, removing the knife from her pants before she sits down. Villanelle comments on Niko's mustache as Eve asks her why she is there. Villanelle begins to sob, asking for help and saying she knows what she is but they make her hurt people. Eve calls her bluff and reveals that she knows Villanelle is Oksana; she knows her history and tells her she is a psychopath. She asks who Villanelle works for and Villanelle tells her that if Eve goes high enough up the chain, they probably work for the same people. Eve shows Villanelle her prison file and asks about the castration and why Villanelle killed Bill. She replies it was because he was slowing Eve down. Eve picks up the knife even as Villanelle warns her not to and Villanelle quickly has her pinned against the fridge with the knife pointed at her neck. Villanelle sniffs her neck and asks if Eve is wearing her perfume. The door opens as Niko and Dom enter. Eve begs for their lives as Villanelle picks up Eve's phone and asks for her PIN ("1234"). Villanelle takes Eve's phone and dress and says hello and goodbye to Niko and Dom on her way out the door.
Eve rushes over to Carolyn's house, interrupting her at dinner with friends and Kenny, who is her son. Carolyn takes her and Kenny into another room and Eve explains that Villanelle has her phone, which gives her access to Frank's interview and his location. She also asks for protection for Niko.
Outside the safe house, police in tactical gear move in. Carolyn and Eve listen from a van as they report back they have a male in need of medical assistance. Eve rushes in to find Max still alive but Frank is dead in the bedroom. He is laid out on the bed, wearing Eve's dress, his knob chopped off.
In Eve's office, Kenny reports that Nadia was picked up in Bletcham by Russian intelligence and was taken to the same prison Villanelle "died" in three years previously. Eve asks Carolyn if they can go to Moscow to question Nadia. Both Kenny and Elena opt out of the trip.
Eve meets Niko at his bridge hall and catches him smoking. He shows her a newspaper with Frank's murder on the front page, pointing out that he was at Bill's funeral and wants to know how many more people have to die. They get in a screaming match and Eve slaps and shoves him. Niko walks away before stopping and telling her they should forget about the fight and get some dinner. Eve tells him she can't; she has to got to Moscow.
In Moscow, Eve and Carolyn take a taxi as they discuss what the Twelve might want and review Nadia's and Oksana's prison files. Carolyn puts on makeup, prompting Eve to ask about Carolyn's Russian contact, Vladimir Betkin, and how well she knows him. They arrive at the hotel and check into their rooms. Eve calls Niko and gets his voicemail. She hangs up without leaving a message.
At the bar, Carolyn and Eve are having drinks before Vladimir arrives. Carolyn gives Eve advice on her personal life, telling her she shouldn't have one because it is a detriment to the people in her life. Vlad shows up and greets Carolyn before introducing himself to Eve. He has another person joining them: Konstantin. Carolyn greets him with familiarity and they soon fall into retelling old stories. Carolyn eventually gets to the matter of Nadia but Vlad is withholding. She brings up the Russian sleeper agent who was assisting Frank and asks if either of them are investigating Victor Kedrin's murder. Carolyn offers an exchange: for a meeting with Nadia, she will provide them with the information they received from Frank before he was murdered. Eve reveals that Villanelle/Oksana broke into her house to have dinner and thinks Nadia can provide information about her. Vlad capitulates to one interview as long as Konstantin goes with them to the prison. As Eve and Carolyn head to their rooms, Eve tells Carolyn that she doesn't like Konstantin.
Eve, Konstantin, and Carolyn arrive in the interview room. Konstantin leaves them alone, saying it is better if it is just them. Nadia enters on crutches and with a broken arm. Carolyn begins questioning Nadia, offering her release from prison and transport to the UK. Eve asks about Oksana and Nadia reveals that Oksana took her place in their plan to escape the prison. Konstantin walks through the door, interrupting Nadia's story about what happened three years prior. He claims the sound in the other room wasn't working but Nadia refuses to speak further on the escape plan. She mentions the name "Anna" and Konstantin commands her to tell them.
Vladimir meets up with Konstantin, Carolyn, and Eve in a car. Carolyn asks Vladimir to grant immunity and safe passage for Nadia so they can get further information. Vlad wants to know the name of the organization behind the assassinations and Eve tells him it is the Twelve. Vlad still refuses to help and exits the car.
Carolyn and Eve are at the bar, drinking. Eve tells Carolyn that she doesn't like Vlad, either. Carolyn reveals that she and Vlad have an "illicit" history together, however, Vlad still has not forgiven her for a plutonium plot he was framed for when it had been Konstantin who was Carolyn's source. Eve apologizes for not liking either of Carolyn's "boyfriends." After Carolyn heads to bed, Eve calls Kenny to see what he found out about Anna. Kenny tells her that Anna was the wife of the man Villanelle had castrated six years previously. Eve asks Kenny to dig up any information on Konstantin and Carolyn.
Eve meets privately with Vlad on a bridge. She pleads with Vlad to give them Nadia and they will release the sleeper agent who helped Frank. Vlad refuses and starts to walk away. Eve stops him by saying she knows who was the real source for the plutonium plot.
Eve calls Kenny, begging for any private information he can find between Konstantin and Carolyn. Kenny calls Eve back that he found letters from Konstantin.
Eve leaves her room at the Hotel Atlasov in Moscow to go to breakfast. She runs into Carolyn returning from being gone all night and wearing the same clothes as the day before. Carolyn tells Eve that Vlad had a change of heart and will be giving them Nadia. Carolyn receives a phone call alerting them that Nadia was murdered. Konstantin joins Eve and Carolyn for breakfast and explains that Nadia was attacked by another inmate, "Natalie." Eve wants to meet "Natalie" but Konstantin laughs and refuses. Konstantin takes his leave, telling them they can stay but they're no longer invited.
As Eve and Carolyn walk the streets of Moscow, Carolyn reveals that Kenny is now in Moscow. They arrive at a shop and are allowed into a backroom where Kenny has set up a temporary office.
At their new office, Eve tries to get the heat to work as she hypothesizes that "Natalie" is actually Villanelle. Kenny volunteers to check CCTV for visitors but Carolyn shuts him down. Eve changes tactics and decides they must find Anna. Carolyn says it is unnecessary and asks Kenny to have Elena fly them back to London since there is nothing left for them in Moscow. Carolyn will remain behind to "tie up" some things. After Carolyn leaves, Eve and Kenny decide to remain in Moscow anyway and Kenny presents Eve with some personal letters of his mother's that he found.
The letters Kenny found are dated from 1977-1978 and are of an explicit nature. Eve is planning to give them to Vlad as proof that he was not the one involved in the plutonium plot but asks Kenny to go through them to see if there might be a code. Kenny also found some old photos, one of which has Konstantin sitting with Carolyn. He provides Anna's address to Eve and she tells him it is okay if he wants to go back to London. He wants to stay and is planning on going through the CCTV cameras at the prison to look for Villanelle.
Eve visits Anna where she works as a language teacher. Eve lets Anna believe Oksana/Villanelle is still dead as she questions Anna on why a secret organization might have recruited Oksana. Anna reveals she has a few letters from Oksana at home.
In Anna's apartment, she gives Eve a large box filled with letters and gifts from Oksana. The letters are all written in French, Oksana's favorite language. Eve pries and Anna reveals that she gave Oksana extra time and attention because everyone else was fearful of her. Oksana would give her gifts of expensive perfume and designer clothes but she did not like Anna's husband, Max, and claimed that Anna only loved him for his penis. One night, when Anna came home, there were balloons and a cake and Oksana had castrated and murdered Max. Eve finally reveals that Oksana is not dead and is currently in Moscow. Eve pulls out the old photo of Carolyn and Konstantin and Anna points out Konstantin as the man who told her that Oksana had died.
Anna gives Eve a bag, saying it arrived a month after Oksana had died. Eve opens it and finds an expensive French coat. Unbeknownst to Anna, sewn into the lining of the coat is a passport for "Marta Poslovina" with Villanelle's picture, credit cards, and money. Eve takes the passport and a picture of Oksana and shoves them into her purse before returning the coat to Anna.
Anna brings Eve some cake to take home. Anna asks her to let her know if she finds Oksana so Anna can forgive her before warning Eve that she is Oksana's type. As Eve is leaving, she turns around and asks bluntly if Anna ever had sex with Oksana. Anna says no and slams the door on Eve.
Eve calls Niko and gets his voicemail. She leaves another message for him, asking if she can see him when she comes home tomorrow. She enters their temporary office and joins Kenny to search through the CCTV footage. She speculates on Anna's and Oksana's relationship. Eve spots a prisoner from behind who walks like Villanelle. Kenny finds another angle and they zoom in on Villanelle's face, confirming that Villanelle was in the prison with Nadia. On the CCTV, Villanelle is led into a visitor's room where Carolyn shows up to meet with her.
Eve and Kenny walk through the streets of Moscow. Eve wants to confront Carolyn about meeting with Villanelle in prison but Kenny is scared of Carolyn. They arrive at Carolyn's hotel and Eve convinces the front desk to give her a key to Carolyn's room. Kenny wants to knock first to make sure Carolyn is not in the room. They find Carolyn's room a mess and Konstantin standing with a hair dryer. Carolyn exits from the bathroom and stops short when she sees Eve and Kenny. Eve states that Villanelle is in the prison. Carolyn explains that she escaped, locked Konstantin's wife in a cupboard, and kidnapped his daughter.
At breakfast, Carolyn tries to send Kenny away but he asks why Konstantin's security isn't looking for Villanelle and Irina. Konstantin reveals that the Twelve want him dead. Eve thinks they should go back to Anna's and calls her. Konstantin decides to go with Eve to Anna's and they will bring her back to the hotel. Carolyn sends Kenny to pack up their equipment, threatening to fire him if he refuses, while she is going to visit Vlad to set up protection for Anna.
Konstantin drives Eve to Anna's apartment, already knowing where she lives without Eve giving him the address. Eve asks Konstantin why Villanelle wants to kill him. He replies that if he tells her, he will have to kill her and starts laughing. Eve starts laughing with him, insisting repeatedly that it is okay for him to kill her. She asks if he is part of the Twelve, which causes him to laugh again. Eve thinks Villanelle wants her but Konstantin says she wants him. Eve accidentally opens the glove box, revealing a gun, and Konstantin promptly closes it again.
Konstantin has pulled over the car for a bathroom break. When his back is turned, Eve grabs the gun from the glove box and points it at him. Eve questions him about Villanelle. Konstantin admits he recruited Villanelle for a private organization and claims he has not seen her in years. Konstantin explains that he wants his daughter, the Twelve want him, and Eve wants them so if Eve leads him to his daughter, she will get everyone. Eve's phone rings with Anna's number but it is Villanelle demanding her passport. Villanelle sets up a meeting at Cafe Radozhny.
Villanelle and Irina are already at Cafe Radozhny when Konstantin and Eve arrive. Irina runs toward her father but Villanelle stops her and takes her hostage, threatening the other patrons in the restaurant if they move. Eve pulls the gun from the glove box on Villanelle. Konstantin offers to go with Villanelle while Eve offers up the cash and passport for Irina. Villanelle calls Eve's bluff because she will not hurt anyone with the gun. Eve sets her gun down. Villanelle, Irina, and Konstantin all tell Eve to throw the passport and money, which Eve does, but the toss falls short. Villanelle has one of the diners bring it the rest of the way to her. Villanelle tells Konstantin that she has to do her job and shoots him in the stomach. Irina jabs Villanelle and manages to get away while Eve picks up her gun and aims it at Villanelle, calling her, "Oksana." Eve asks her to come with her, just the two of them. Villanelle backs away and flees.
At the airport, Carolyn informs Eve and Kenny that Konstantin has died. Eve checks her voicemail and hears a message from Elena that a young man (Sebastian) was found dead at an apartment in Paris with the same chemical in his system that killed Carla De Mann. Elena has uncovered that one of the apartments is paid for by the same account that was paying off Frank. Eve lies to Carolyn and tells her it was Niko on the phone. Carolyn confronts them about giving Vlad her love letters to Konstantin and fires them both. Carolyn and Kenny board the flight to London but Eve takes off in another direction.
Eve heads to Villanelle's apartment in Paris. She runs into Villanelle's neighbor, Madame Tattevin, who knows Villanelle as "Julie." She mistakes Eve for someone who has been paying her to keep records on Villanelle and invites her in to show her all of Villanelle's comings and goings. Eve gives Madame Tattevin her phone number and asks her to text her when Villanelle returns. Eve leaves Madame Tattevin's apartment and tries to get into Villanelle's. Madame Tattevin offers up a key.
Eve enters the apartment and takes a look around. She opens a wardrobe and finds various uniforms and wigs along with a drawer full of weapons. She opens the fridge, finds it stocked with champagne, and grabs a bottle. In another wardrobe, she discovers designer clothing and her own green scarf. She starts tearing the clothes off their hangers and goes into a rampage, making a mess of the apartment and breaking bottles.
The sound of the door opening sends Eve to the weapons drawer where she grabs a gun. She comes out to find Villanelle standing in front of the ransacked wardrobe. She threatens to kill Villanelle but Villanelle again calls her bluff. They sit down across from each other, Villanelle at the vanity and Eve on the edge of the bed. Eve admits that she thinks about Villanelle all the time and wants to know everything about her. Villanelle admits that she masturbates about Eve. Eve lies down on the bed, exclaiming, "God, I'm tired." Villanelle picks up the gun and lies down next to Eve on the bed. Eve asks if she is going to kill her and Villanelle promises she won't before setting the gun on the floor. They turn on their sides and face each other. Eve admits she has never done anything like this before. Villanelle says she knows what she is doing and moves closer, stopping when she feels a blade poking into her stomach. Villanelle still does not believe Eve can do it. Eve says she can and stabs her before rolling Villanelle onto her back and straddling her. Villanelle begs her not to pull the blade out but Eve does so and Villanelle begins to bleed all over the place. Eve runs to the kitchen for a towel and Villanelle starts shooting at her. When Eve finally makes it back to the bedroom, Madame Tattevin stand there, informing Eve that Villanelle has left.
