After being sent into the future by evil wizard Aku, young samurai Jack makes a quest to return to the past and undo the destruction caused by the wizard. Along the way Jack enlists allies to defeat some of Aku's henchmen and other villains before getting to the top dog to defeat him and find the portal that can return Jack to his own time. `Samurai Jack' was created by Genndy Tartakovsky, who had previously created `Dexter's Laboratory', one of Cartoon Network's first original series.
