Jack joins a group of gangsters who work for Aku. He also agrees to help steal the heavily protected crystal that can give Aku power over the whole planet. Fortunately Jack has not become a traitor, but has his own plans of how to hand over the swag.
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!'.
