Eve struggles to identify her lead in The Twelve. Villanelle gets her mojo back - she decides to be good by embracing what she's good at - killing. Carolyn discovers an old acquaintance in Cuba and decides to go rogue.
Villanelle is released from prison with the help of Hélène, who tells her that it is impossible to leave the Twelve and gives her a new assignment in Cuba.
In Havana, Cuba, Villanelle kidnaps Carolyn, who has traveled there to interrogate Rustem, a member of the Twelve who survived an assassination attempt ordered by Hélène. She assaults Carolyn but spares her life after Carolyn reveals to Villanelle that she has known her since she was a child in the orphanage. Carolyn encourages Villanelle to interrogate and torture Rustem, who gives up the name of a restaurant before being killed by Villanelle.
Carolyn runs into Lars at the restaurant, who is surprised to see Carolyn and flees. She tells Villanelle that she was in a relationship with Lars and that he is likely headed for Berlin.
Meanwhile, Eve meets Hélène who confirms that Lars is in fact her target, and challenges Eve to find him before she does. While following up on a lead in Paris, she is contacted by Hélène who invites Eve to her apartment and taunts her with the news that Villanelle is out of prison. In response, Eve kisses Hélène and leaves the apartment.
