Bolt is reunited with Penny when a fire breaks out on the set (accidentally caused by the replacement Bolt) and he goes to help her. Fire fighters get them out of the building. Pennys agent wants to use the accident for publicity and for Penny and her mother to be producers of the show. Penny quits the show and shes replaced by another actress and an identical dog replaces Bolt. The show starts a new story with Pennys character undergoing plastic surgery and aliens as the antagonists (as suggested by the pigeons that Bolt meets in Hollywood). Penny and her mom move to a new house and they adopt Mittens and Rhino . The last scene is Penny and Bolt playing outside.
