On his 18th birthday, Goku (Justin Chatwin) receives a mystical Dragonball as a gift from his grandfather. There are only six others like it in the whole world, and legend has it that whomever possesses all seven will be granted one perfect wish. When the arrival of a dark force triggers a tragedy, Goku and his companions (Chow Yun-Fat, Emmy Rossum) are propelled into an epic quest to collect the seven Dragonballs and save the Earth from destruction.
