Psychopathic Villanelle—a young and prolific assassin—leaves a trail of high-profile murders across several countries. MI5 officer Eve Polastri connects a new assassination in Vienna to a series of such killings which she has been researching in her own time.
There are hints that Elena and Kenny may have a romantic relationship. Villanelle breaks into Eve’s home to talk to her, and takes her phone, which Villanelle uses to track down Frank at the safe house and kill him.
Villanelle approaches Carolyn and offers to turn into a source for MI6; Carolyn rejects her when she can’t give any data. Villanelle then, at that point approaches Eve and requests that she recover a bundle Konstantin had stowed away to help his departure.
Villanelle is elevated to Keeper by Hélène, a specialist of the Twelve, and requested to kill a Romanian lawmaker. Baffled and disappointed that the work is the same, she moves toward Konstantin and requests to join his arrangement to flee.
Villanelle’s return to her family home in Russia is met with surprise and suspicion from her extended family. She bonds with her reclusive brother Pyotr and her Elton John-obsessed half-brother Bor’ka, and reunites with her mother Tatiana.
