Bolt (John Travolta) has spent his entire life as a famous TV superdog. But, when he is accidentally shipped from Hollywood to New York City, he discovers that his powers aren't real and must rely on his new friends Mittens (Susie Essman), a jaded housecat, and Rhino (Mark Walton), a TV-obsessed hamster. As Bolt sets out on a cross-country mission to reunite with his owner Penny (Miley Cyrus), he learns that the only thing you need to be a hero is heart. Directed by Byron Howard and Chris Williams.
