Gangster No. 1 enters the psyche of an unrepentant mobster and reveals the madman within. Bettany gives a brilliantly eerie performance as a ruthless mobster who slugs, claws and kills his way to the top. But when he learns that the former mentor (Thewlis) he put in prison is about to get out, this self-made monster must not only face a man whose life he ruined but the twisted remnants of his own demented conscience as well.

Based on the stageplay by Louis Mellis and David Scinto.
