An apparent murder victim becomes the object of Quincy's thorough investigation and identification when his mother and sister insist that he is still alive.

Two customs officers want Quincy's help in catching arresting a diamond smuggling ring. A courier they were following was killed when a bus at the airport and, as Quincy is going to a Las Vegas to judge a Miss Coroner Contest; they want him to take the couriers place. He has to deliver the diamonds to a known mobster, something he really, really does not want to do!
