Harry is the latest generation of the Crumbs, famous and extremely talented detectives. Unfortunately, talent seems to have skipped a generation, and Harry is reduced to "gumshoe" work at a remote branch of the Crumb detective agency. Back at headquarters, Crumb executive Elliot Draison hatches an evil plan, which requires the inclusion of an incompotent detective. With Harry Crumb on the case, Draison thinks everything will run fine for him. Despite his best efforts, Crumb actually makes some headway in the case...

A financier [Chevy Chase] meets a spurned lover [Demi Moore] and agrees to take her to a business meeting. On the way there, they run a stop sign in a tiny town in the middle of nowhere. They are arrested and taken to the local court. But all is not as it seems: the courthouse and the "prison" are a maze of zany booby- traps and deadly contraptions. The antics of the captured couple as they try to escape from the mad judge and his bizarre family make up the rest of this unusual film.
