The film studio is so disgusted by the new cut that they attempt to block its distribution. Homer and Mel steal the only print of the film and escape the studio lot with the executives pursuing them. Commandeering the old Mad Max car from the Hollywood Auto Museum, the Simpsons and the movie star careen through the streets, causing all sorts of destruction. Can they escape with the print intact? Does Mr. Smith ever get to go to Washington? Why doesn't Mel Gibson have an accent anymore?
