Gohan and Oolong search for the magical Dragon Balls and their radar shows them that the orbs are being gathered by another, unknown party. They investigate near a large wall of ice where Piccolo is training. Meanwhile, the mad scientist Dr. Kochin, having successfully gathered all of the Dragon Balls, summons the eternal dragon Shenron and wishes for Dr. Wheelo and his lab to be released from the ice. The ice breaks away as a building emerges and Gohan and Oolong are attacked by Dr. Kochin's "bio-men". Piccolo saves them but is overcome by three mysterious warriors while Gohan and Oolong escape.
