Tony is a notorious gangster with a big problem. He has woken up in an abandoned farmhouse, with blood on his shirt, and no memory of how he got there. He stumbles into a small town and discovers he’s in an Italian village that seems to be lost in time.

When a broke young couple rent a room in an elderly couples London house it becomes apparent no one is what they really seem.

The plot follows detectives Karl Roebuck and Elise Wasserman working together to find a serial killer who left the upper-half body of a French politician and the lower-half of a British prostitute in the Channel Tunnel, at the midpoint between France and the UK. They later learn that the killer—who comes to be nicknamed the "Truth Terrorist"—is on a moral crusade to highlight many social problems, terrorising both countries in the process

Hannah plays DI Jack Cloth, who is called in to investigate an apparent series of serial killings alongside his new partner, DC Anne Oldman, described as a "plucky, no-nonsense sidekick". Playing with the cliches and conventions of British police dramas, subplots include Cloth dealing with visions of his dead wife and the bisexual DC Oldman coming to grips with her feelings for both her female fiancee and Cloth.
