The director of an all-girl's boarding school is playing at a clandestine casino which is robbed. The thieves flee and hide out in disguise at the boarding school, where the school director helps hide them in exchange for the loot. While there, the thieves fall in love with the school janitor and rescue one of the schoolgirls from her boyfriend.

In this crime parody, two fumbling detectives try to solve a murder without getting murdered, seduced, or outwitted in the process.
