Brooding psychological thriller, starring Christian Bale. Trevor Reznik (Bale) is a factory machine-operator who is suffering from crippling insomnia. His weight has plummeted, he suffers from hallucinations, and he finds himself unable to concentrate at work, leading to a horrific accident involving one of his co-workers. Ostracised from the other men at the factory, Reznik starts finding threatening notes and begins to fear that someone is trying to kill him. Is his paranoia part of his psychological breakdown, or is it possibly justified?
