While driving through a city, Lightning and Mater observe the filming of a zombie sci-fi film. The crew notice Lightning and decide to cast him as a deputy, although the filming goes awry due to his bad acting. Meanwhile, Mater impresses the crew and is given multiple roles, to Lightning's jealousy. Mater later explains to Lightning that he can't be good at everything, which comforts him. The next day, the duo find out that the entire story was rewritten to be a musical instead, and Ivy has been cast as a leading role. Lightning and Mater, fired from the film, drive away. (thetvdb.com)
