Series about a murder investigated by both sides of the line, cops and criminals, and the opposing methods they use to solve it. But the real line is the morality within each character and how far they will go before they cross it.

In the first episode, DI Gabriel (Chiwetel Ejiofor) has just returned to work after being shot on an undercover job; his partner was killed and Gabriel suffers amnesia with a bullet lodged in his head. He leads the police investigation of the murdered drug baron Harvey Wratten and finds himself in a race with the other side of the line, the drug dealers who want to know who killed their boss.

Thriller drama also starring Christopher Eccleston, Rafe Spall, Lesley Sharp and Kierston Wareing. Show less
