Dragon Ball Z Movie 01: Ora no Gohan wo Kaese!!

Garlic Jr. is gathering the Dragon Balls to obtain eternal life, and the four-star ball attached to young Gohan's hat makes the child his next target. After his servants attack the Son family and kidnap Gohan, Goku follows the Dragon Radar to Garlic Jr.'s fortress to bring his son home.

Piccolo and Kami have their own reasons to confront the enemy, but the situation becomes far worse when Garlic Jr. succeeds in making himself immortal. Even overwhelming force may not be enough against an opponent who cannot die, forcing Goku and his unlikely allies to face a gateway capable of swallowing everything around it.
