Detective Joe Stone works for the Strategic Investigation Unit in London. When the daughter from one of two rival Mafia families operating in his area is kidnapped, he is ordered to investigate.
Joe is struggling with the disappearance of his girlfriend Gemma almost a year ago. He doesn't know if she is alive or dead but he's sure that one of the Mafia families knows exactly what happened to her.
As the body count rises, it's clear that the psychopath wants to start a gangland civil war. When the investigation closes in on the suspect it's then Joe who becomes the target.
