Imagine calling the cops to restore law and order - and Jerry Lewis shows up? In his first film without longtime partner Dean Martin, Lewis plays Sidney Pythias, a bumbling janitor caught up in the middle of a gang rumble. Mistaken for a member of the switchblade set, Sidney is encouraged to undergo a 180-degree transformation - from street hoodlum to full-fledged policeman! Darren McGavin is the reluctant law enforcement officer who must mold Lewis into a respectable man-in-blue at the Police Academy. But with all the chaos, disorder and trouble Sidney manages to unleash during his training and development, just who will the police call for help?!
