Luther

A self-destructive near-genius, Luther might just be as dangerous as the depraved criminals he hunts. Luther follows his own moral code as much as the rules of criminal law. But he quickly becomes locked in a lethal battle of wits with Alice (Ruth Wilson), a beautiful, highly intelligent mass murderer, and his decision-making process becomes increasingly murky. The strain begins to tell as he's drawn deeper and deeper into a series of horrific murders, and the shadow of a former case threatens to bring him down. Forced to face his own capacity for violence, he struggles with why his wife left him and what draws him to Alice. As the stakes get higher and more personal, Luther's lonely path pulls him towards the very edge of temptation. (official distributor synopsis)
