For super-dog BOLT (voice of John Travolta), every day is filled with adventure, danger and intrigue at least until the cameras stop rolling. When the star of a hit TV show is accidentally shipped from his Hollywood soundstage to New York City, he begins his biggest adventure yet a cross-country journey through the real world. Armed only with the delusions that all his amazing feats and powers are real, and with the help of two unlikely traveling companions: a jaded, abandoned housecat named Mittens (voice of Susie Essman) and a TV-obsessed hamster in a plastic ball named Rhino, Bolt discovers he doesn't need superpowers to be a hero.
