Larry Wilson (William Powell) is a wealthy businessman. He's also so incredibly boring that his wife, Kay (Myrna Loy), wants a divorce. But when Larry gets knocked on the head, he discovers that he isn't Larry Wilson at all. He's actually George Carey, a con artist, and his life as Larry has really been a case of amnesia. Now back to his old ways, George plans a con to rob an entire town of their money. But George's fiery ways make Kay reconsider the divorce.
