When George Miller falls asleep, people die. Brutally. The problem arises from the fact that when he was born, Vito Minelli (a smalltime crook) was also born. The two of them died at exactly the same moment and they came back in the same body. Thus, when placid, pleasant George is asleep the wicked and restless soul of Vito takes over and sets upon a mad killing spree. Luckily for troubled George, a young psychiatrist realises the truth behind George's nightmares and protects him from the prying eyes of the police.
