Action meets romcom. Assassin Maisie Baxter meets her match in mysterious hitman, Agent Perseus, as the two rivals team up to uncover a conspiracy.
Maisie Baxter has a particular set of skills honed over a very successful career. She's determined not to let being the number one ranked hitman at the UK's second-best assassin agency get in the way of her having the social life of any other 30-something Londoner, but it's tough to date when your hours are extremely unpredictable and you can't share any details of your day.
So it's lucky that Maisie just met a cute guy at work. A really cute, charming guy who she can actually talk to about work. Not so lucky that he works for her rival and keeps getting to her targets before her.
When it becomes clear that these chance meetings are no coincidence and they can't trust anyone, Maisie and the mysterious (but seriously, super cute) Agent Perseus are going to have to put aside their professional rivalry - and their building sexual tension - to uncover a conspiracy that goes all the way to the top.
