A dopey rabbit named Fu rescues Shifu, a martial arts master, from a fatal attack and is telepathically granted the ultimate kung fu power. In return he promises to bring the tablet of Shifu's martial arts academy to Shifu's daughter, Penny. On the way, thieves ambush Fu, and without realizing it he is rescued by Penny. The two become traveling companions and reach the academy, only to find that the evil Slash has seized it. Penny faces Slash in a kung fu showdown to win back her father's school, and Fu will have to reveal his hidden power to defeat Slash and keep his promise. The result is an action comedy adventure told as a single feature film.
