Eve attempts to rebuild her life, having been shot and left for dead in Rome by Villanelle. Villanelle, believing Eve to be dead, is approached by an old foe who offers her a new opportunity.

Eve strikes up an unlikely alliance with Kenny’s colleagues at the Bitter Pill. Villanelle finds that management isn’t all it’s cracked up to be.

Villanelle agrees to a job that will take her back to London. Carolyn’s Moscow contacts come in useful when Eve and the team uncover a potential lead.

It is Eve’s birthday, and she is trying to patch up things with Niko. Villanelle receives good news about her upcoming promotion but can’t shake the feeling that there is still something missing from her life. Dasha seeks a solution to Villanelle’s erratic behaviour.

Villanelle returns home to Mother Russia to try to find her family. Perhaps a new connection to her roots will give her back what has been missing in her life.

As the investigation continues, Carolyn finds out that information is being withheld by those close to her. Eve finds a lead which might bring her closer to Villanelle, but Villanelle has had enough and decides on a different path.

Eve finds a clue to Villanelle's whereabouts in the most unlikely of places, Villanelle and Dasha work together on a kill, and the pressure is getting to Konstantin.

Konstantin makes a break for it, while Eve and Villanelle try to work out what the future may hold for them - together or apart.
