The stooges witness an armed robbery and are brought in by the cops as suspects. After passing a lie detector test, the boys are freed and go back to their jobs in a Cafe. When one of the robbers comes into the Cafe, the boys recognize him and along with their friend Gladys trail him to a spooky house in the country where the crooks are hiding out. The bad guys abduct Gladys and the stooges must rescue her.

Shemp dies but cannot get into heaven until he reforms Moe and Larry. He returns to earth as an invisible spirit and sets out to prevent the other two stooges, who are in league with the devil, from selling a phony invention (a fountain pen that writes under whip cream) to a rich couple. Shemp sabotages Moe and Larry' plans and makes it through the pearly gates.
