A big-city salesman, Albert Tuttle, arrives at the spooky mansion of tyrannical millionaire Cyrus Wentworth hoping to sell him an expensive life insurance policy. Tuttle is surprised to find that the prospective customer is lying in his coffin surrounded by greedy heirs awaiting the reading of his will. A mysterious killer is at large, picking off the conniving relatives one-by-one. Trapped by a raging storm, the salesman becomes involved in the family's double-crossings and death threats. In a spectacular climax atop a mountain observatory, Tuttle comes face-to-face with the murderer. Bela Lugosi manages to steal the show as the creepy butler. While his presence is a dark shadow against the often laughable antics of the ravenous treasure seekers, Lugosi ends up with the film's funniest lines.

A mystery spoof in which Haley plays a nonchalant salesman who is mistaken for a private detective at a creepy estate with a built-in observatory.
