In his travels Jack comes to a tavern and a crying tavern owner. Then shadowy figures attack but Jack discovers they are teenagers, the 'Children of Aku', under a magical musical spell. Knocking one out and following them in disguise, jack finds their rave and a sinister DJ playing the music. The DJ spots Jack and a fight ensues. Jack takes the fight directly to the DJ who is his near-equal. When Jack gets the upper hand the DJ dons a speaker-battlesuit but Jack regains his lost sword at the last minute and triumphs, freeing the children.
Made by Genndy Tartakovsky, this cartoon tells the story of a great warrior displaced to the distant future by the evil shape-shifting wizard Aku. The world has become a bleak place under the rule of Aku, segregated into fantastic tribes and ruled by Aku's evil robot warlords. Jack travels this foreign landscape in search of a time portal that can return him to his home time so he can 'undo the future that is Aku!'.
