Frank Albertson is a less than successful private investigator who, with his wife Sunny, tries to claim a John Doe as their long lost relative, Uncle Charlie. If they can get the man declared as their uncle, they will be able to collect an inheritance left to him. By the time they get to Nevada to claim the body, they learn that they are, in fact, the third to have claimed John Doe's remains as being their relative. The sheriff is stuck in the middle of it all. After Frank salts the accident site with some of his uncle's possessions, he is caught out and soon finds himself behind bars. Gradually, the other claimants are eliminated with Frank and Sunny triumphant - or so they think.
