Introduction:

A girl named Penny (Miley Cyrus) and her dog Bolt (John Travolta) star on a hit television series Bolt in which the titular character has various superpowers and must constantly thwart the evil plans of the nefarious Doctor Calico (Malcolm McDowell). Because Bolt has lived his entire life on a soundstage, and believes he really is his fictional counterpart, he doesn’t know how to live like a normal dog. After filming completes for one episode, Bolt escapes from his on-set trailer mistakenly believing Penny has been kidnapped by the television villain. He attempts to break through a window, knocking himself unconscious as he falls into a box of styrofoam. With no one aware Bolt is in the box, it is shipped from Hollywood to New York City. In New York, he meets Mittens (Susie Essman), a female alley cat who bullies pigeons out of their food. Because Mittens is a cat similar to one owned by Doctor Calico, Bolt forces her to help him get back to Hollywood, and the two start their journey westward. Meanwhile, in Hollywood, Penny is deeply saddened over Bolt’s disappearance but is forced by the studio to continue filming with a Bolt lookalike. Along the way, Bolt starts to notice that his superpowers aren’t working, but he rationalizes this is the effect that styrofoam has on his body (much like Kryptonite affects Superman).
