The Stooges are pest exterminators who decide to drum up business by planting mice, moths, and ants in an unsuspecting house. Shemp and Larry carry around a large bag full of cats. They select a fancy mansion where a high society dinner party is being held. The hostess (Margie Liszt) has several dozen pies and pastries set out on tables. After successfully infesting the house with pests, the trio are predictably hired to clean up their own mess without interrupting the party.
