A tough Washington DC cop (Gene Hackman) teams up with a man with a multiple personality disorder (Dan Aykroyd) who speaks in the voices of Tweety Bird, Captain Kirk Pee-wee Herman, Ricky Ricardo, and even the Wicked Witch of the West. Together they pursue a gang of marauding neo-Nazis in an attempt to capture a porno film featuring Adolph Hitler in bed with a man who is about to be elected chancellor of West Germany.
