After eavesdropping on his doctors as they discuss another patient, George (Rock Hudson), a middle-aged hypochondriac, leaves a hospital visit believing he's terminally ill. Assuming he'll soon be dead, George enlists his friend, Arnold (Tony Randall), to help him find a new husband for his wife, Judy (Doris Day). They eventually settle on Bert (Clint Walker), a successful businessman. But George's odd behavior makes Judy suspect he's covering up an affair.
