This cruise is suppose to have some celebrities among the passengers. But the PR employees (Debbie Reynolds and Marilyn Michaels) booked them on a different cruise. So they end up impersonating celebrities. A celebrity (Carole Cooke), doing research for her role as Florence Nightingale by working as Doc's (Bernie Kopell)'s nurse, meets a passenger (Forrest Tucker) who doesn't like show business types. A man (Richard Kline') who was accused of a crime and was acquitted, goes on the cruise with the lawyer (Vicki Lawrence) who defended him. And they make admissions to each other, she that she loves him and he that he actually committed the crime he was charge with.
