Eve is trying to patch things up with Niko; Villanelle receives good news about her upcoming promotion but can't shake the feeling there's still something missing from her life; Dasha seeks a solution to Villanelle's erratic behavior.
Eve's life as a spy is not adding up to what she had hoped it would be when she started. She is a bored, very smart, MI5 security officer who is very desk-bound. Villanelle is a very talented hugger, mercurial in mood, who clings to the luxuries of her job. Eve and Villanelle go head to head in a fierce game of cat and mouse, each woman equally obsessed with the other as Eve is tasked with hunting down the psychopathic assassin.
