When Guy’s memory returns with the ill-timed mention of a name, he remembers a sinister time before. He tried to kill, Kathryn, his wife. Twice.
Guy can’t remember trying to kill his wife, Kathryn. Nor that he did it because she slept with his friend and her boss, Leonard. He crashes his car on the way to her intended murder scene and suffers amnesia. Kathryn helps him recover, but he remains an amnesiac and finds making love to her a totally new experience. When she mistakenly calls him Leonard in a torrid moment, old feelings of hate and anger flood his mind. With a knife clenched between his fingers, he tries and fails to murder her for a second time. Homeless, he befriends Kathryn’s sister, Jeni. She tells Guy that Leonard is a violent gangster and once more, he and Kathryn are conducting an affair. Jeni and Guy find solace together, and as he releases his guilt and anger, his memory returns. Appalled by his actions, Guy realises he’s in danger and flees to France to stay with an old friend. Leonard follows, kill’s Guy’s friend and abducts Guy, dragging him to an old warehouse, where Kathryn waits to kill him. In a surprising volte-face, Kathryn and Guy become reconciled and live briefly as husband and wife. But violence looms when Leonard suddenly drops in.
