After defeating a band of robotic cat-demons Jack travels the land and finds himself in the area where he grew up. As he tours the ruins he has flashbacks to a day spent pursuing a locust in the company of a young girl, witnessing a wandering warrior defeat four men on a bridge, having his parents greet him, and tricking three bullies.
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!'.
