While being held hostage at the army base, Stanley overhears the address of the warehouse being used for the illegal arms deals. Following an escape, the Stupids go to the warehouse, where they expect to find Sender and the stolen mail. They confront Neidermeyer and his terrorist associates in a battle, resulting in some explosions that cause the police to investigate the warehouse. Stanley offers what he perceives to be heroic advice about how Sender can repent his evil ways, but he takes them as road directions. In the end, the Stupids return home.
