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 to get back to his owner and co-star, Penny (voice of Miley Cyrus).

Armed only with the delusions that all his amazing feats and powers are real, and the help of two unlikely traveling companions—a jaded, abandoned housecat named Mittens (voice of Susie Essman) and a TV-obsessed hamster named Rhino (voice of Mark Walton)—Bolt discovers he doesn't need superpowers to be a hero.
