A girl named Penny and a dog named Bolt, who has various superpowers, must constantly thwart the evil plans of the nefarious Doctor Calico. However, little does Bolt know he is actually just a star on a hit television series called Bolt. To gain a more realistic performance, the TV show's producers have deceived Bolt his entire life, arranging the filming in such a way that Bolt believes the television show is real and he really has superpowers. After filming completes for the latest episode, Bolt escapes from his on-set trailer when he mistakenly believes Penny has been kidnapped by the television villain. He attempts to break through a window, knocking himself unconscious and falls into a box of styrofoam peanuts. With no one aware Bolt is in the box, it is shipped from Hollywood to New York City. In New York, he meets Mittens, a female alley cat who bullies pigeons out of their food. Bolt, convinced Mittens is an evil nemesis who works for Doctor Calico, forces Mittens to help him get back to Hollywood, and the two start their journey westward on a truck. Meanwhile, in Hollywood, Penny is deeply saddened over Bolt's disappearance but is forced by the studio to continue filming with a Bolt lookalike. As their adventure proceeds, Bolt starts to notice that his superpowers aren't working, and rationalizes this is the effect that styrofoam has on his body.Surprised at his first feelings of both pain and hunger, Bolt is shown by Mittens how to act like a cute, but needy dog, and is rewarded by food. They meet Rhino, a fearless, TV-obsessed hamster and huge Bolt fan who joins their team. Mittens tries to convince Bolt that his superpowers aren't real, but their discussion is cut short by the arrival of Animal Control, who captures them both and transports them to an animal shelter. After being freed en route by Rhino, Bolt finally realizes that he is just a normal dog, but regains his confidence after Rhino (oblivious to this revelation) gives him a pep talk. They rescue Mittens from the shelter and escape, allowing them to continue their journey. Along the way, Bolt learns to enjoy typical dog activities (such as hanging his head out the window and playing fetch), but Mittens refuses to go farther than Las Vegas. She tells Bolt that his Hollywood life is fake and there is no real love for him there. Her emotional rant reveals that she was once a house cat, but was abandoned by her previous owner and left to brave the harsh streets alone and declawed. Bolt refuses to believe that Penny doesn't love him, and continues on alone, wishing Mittens the best. Rhino, learning of Bolt's departure, convinces Mittens that they must help him, and the two set off to find Bolt once again.Bolt reaches the studio, finding Penny embracing his lookalike. Unaware that Penny still misses him, and that her affection for the lookalike was only a part of a rehearsal for the show, he leaves brokenhearted. Mittens, on a gantry in the studio, sees what Bolt does not - Penny telling her mother how much she misses Bolt. Realizing that Penny truly does love Bolt, Mittens follows Bolt and explains. At the same time, the Bolt-lookalike panics during filming and accidentally knocks over some torches, setting the sound stage on fire and trapping Penny. Bolt arrives and reunites with Penny inside the burning studio, being rescued as they succumb to smoke asphyxiation.Penny and her mother subsequently quit the show when their agent attempts to exploit the incident for publicity purposes. Penny herself adopts Mittens and Rhino, and moves to a rural home to enjoy a simpler, happy lifestyle with Bolt and her new pets. The show continues, but with Bolt's original replacement and a new replacement for "Penny" with her appearance being explained in the show as being serious injuries necessitating her undergoing facial reconstruction surgery, and adopting an alien abduction storyline (one that even Rhino finds unrealistic, and Bolt finds "redonkulous").
