On his 18th birthday, outcast high schooler Goku discovers his grandfather's brutal murder and learns he is the last protector of the mystical Dragonballs. Teaming with genius Bulma and desert bandit Yamcha, he seeks Master Roshi to stop the alien Namek lord Piccolo's resurrection before the eclipse. As Goku trains to unlock his hidden power, he uncovers a devastating truth: he is not human, but a Saiyan sleeper agent sent to destroy Earth. Now Goku must master the balance of time and choose his own destiny—savior or destroyer—before Piccolo rises and the world ends.
