The Stooges are inventors desperately trying to obtain a patent for their fly catching invention. Whilst learning they must catch 100,000 flies to get their patent, their conversation is overheard by several crooks across the hallway. Unfortunately, the crooks think Curly has $100,000. A flirtatious woman (Christine McIntyre) who is part of the nest of crooks corners the gullible Curly and tries to finagle the non-existent money out of him. When he confesses that the 100,000 are indeed flies and not dollars, she turns against him, and has the crooks go after the Stooges.
