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.

From Walt Disney Animation Studios comes Bolt, the tale of a superstar TV pup (voiced by John Travolta) who gets plopped in the middle of America with seemingly no way back to the glam and glitz of Hollywood. Thanks to his starring role on a hit television show, Bolt the pooch has become a household name. But Bolt has bought into his own heroic image, now believing that he really possesses the super-canine powers of his fictional television series. When he's accidentally shipped from Hollywood to New York City, he must rely on the help from his two newfound friends -- an abandoned house cat named Mittens (voiced by Susie Essman) and a television-addicted hamster named Rhino (voice of Mark Walton) -- as he embarks on a cross-country quest to get back to his owner (and co-star), Penny (voice of Miley Cyrus). - Jeremy Wheeler, All Movie Guide (Source)
