What's the Worst That Could Happen?

A billionaire (DeVito) catches a thief (Lawrence) robbing his mansion. To get even with him, he takes the thief's lucky-charm ring, telling the cops that it's his own ring. Deprived of his good-luck charm, and faced with a future of bad luck, the thief begins wreaking revenge on the tycoon. The story becomes a battle of wills as the thief tries to get his most treasured possession, his luck, back from a man who has everything.
