In the distant past, a Japanese samurai embarks on a mission to defeat the evil shape-shifting wizard Aku. Before he can complete his task, though, he is catapulted thousands of years into the future. He finds himself in a world where Aku now enjoys complete power over every living thing. Dubbing himself "Jack," he sets out on a new quest--to right the wrongs that have been done by his enemy and to find a way back to his own time so he can destroy the evil for good.
