Known for his brutally violent policing tactics, Michael Clarke is a suspended police officer sent undercover to infiltrate the notorious London criminal enterprise of Terence Turner (Patrick Connolly), with the task of bringing the gang boss to justice. Chief Inspector Hawkins (Tim Berrington) and Baker (Ali Bastian) watch on as Clarke struggles to keep his cover when he finds himself getting dragged deeper into a world of failed operations, people trafficking, murder and extortion. Turner and his son Gavin (Simon Cotton) have their suspicions about the ex-copper but veteran mobster Griffith vouches for him. Clarke's headstrong attitude might see him bring the Turners to justice or his violent tendencies could jeopardise the police operation and his own life.
