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 travel 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.
