The film is about Bolt (John Travolta), a small white German Shepherd who has lived all his life on the set of a TV show in which he portrays a superhero dog. As a result, he thinks that his superpowers, and events on film, are real. When he is accidentally shipped from his Hollywood soundstage to New York City, he embarks on a cross-country journey to reunite with his owner and co-star, Penny (Miley Cyrus). Along the way, Bolt teams up with a jaded housecat named Mittens (Susie Essman) and a TV-obsessed hamster named Rhino (Mark Walton) that also happens to be an extreme Bolt fanboy, and eventually he discovers that he doesn't need superpowers to be a hero.
