The Great Demon King Piccolo is all set for world domination, but first, he needs to gather the seven Dragon Balls to restore his youth and power. Son Goku and his friends pit themselves against this heartless monster, but it's looking more and more grim for the side of good as Piccolo picks them off one by one. Their only hope is a martial arts move known as the Mafu-Ba, a technique that managed to imprison Piccolo many years ago. Unfortunately, the move is so powerful that it killed the last person who used it. That won't deter Kame-Sen'nin and Tenshinhan from trying the killer move though, even if it means forfeiting their own lives in the process!
