The movie starts with Piccolo training hard, when he is attacked from behind by many enemies, all of which defeat him easily. He is attacked by many powerful energy beams, and seemingly dies.

We then go to Goku’s house where Gohan sits peacefully, doing some routine studying and working hard as ever. He is fascinated by the results of the information he’s receiving from the book. Chi-Chi calls Gohan in for dinner, before the Ox-King arrives with his hands full of present., Gohan goes to greet him, and happily says hello. Suddenly, Ox falls onto his knees revealing a mysterious monster of some sort standing behind him. The monster is after the Dragonball on Gohan’s hat, but Chi-Chi won’t let him touch her son. Some more monsters join the scene, all of which are after Gohan. Chi-Chi lunges into the one who seems to be the leader, but is pummeled straight to the floor, as Gohan is captured, and taken away by the four monsters.

Goku arrives on the scene shortly after everyone leaves, to find his wife and father-in-law on the floor in agony. He quickly sees to their needs, then takes off in search of his son.

The leader of the monsters is sitting on his throne, announcing that he almost has all the Dragonballs, and is going to wish for eternal life. The monster is Garlic Jr, and his intentions are purely evil. Gohan whines, but everyone laughs in his face. Garlic can sense some hidden power in him though, and invites Gohan to be his disciple.

Goku grabs the Dragon radar, and locates his son, before soaring off to rescue him.

Gohan manages to run off from his captors, exploring the palace, and finding some sort of alcoholic fruit. He eats it, and goes through a weird dance scene where he is totally drunk, dancing around with dinosaurs, etc. He ends it by falling asleep on Garlic Jr’s throne, much to his ‘Babysitters’ annoyance. Suddenly, someone shouts out that the final Dragonballs have been collected.

Garlic Jr summons out Shenron, and quickly wishes for immortality before anyone can thwart his plans. Getting the new power gives Garlic Jr a new arrogance about him, with a new burst of power making him stronger than ever. Goku arrives on the scene, but it is far too late, the wish has already been made. Garlic Jr mocks him, then walks off, leaving Goku to battle his minions. Before the fight starts though, Kami arrives, meaning that Piccolo isn’t dead. He explains that he beat Garlic Jr’s father to the throne of Earth’s guardian, and knows that the only reason that Garlic is here is to revenge his fathers defeat. Garlic was sentenced to be sealed away for eternity by the previous Earth’s guardian.

Goku realizes where Gohan is, and races into the building, leaving Kami to fight Garlic Jr. The Saiyan is ambushed by Garlic Jr’s three monsters, and they all fight viciously for a while, with neither of them able to gain any sort of advantage on the apposing force. Goku fights them all, and even though it is three-on-one, he still manages to overcome them for a fair bit of time. He knocks them all to the floor, and demands one of them to tell him where Gohan is. Before an answer can be given, the other two minions attack the Saiyan with energy beams, with him seeing them too late to put up any sort of defense. Some how they are deflected away though. A silhouette is revealed. It’s Krillen! Another power arrives on the scene,this time it’s Piccolo! Krillen runs off from him, scared out of his mind. Suddenly, some sort of liquid drops on Krillen’s head. Gohan is leaking on him!

Kami and Garlic Jr continue the ferocious battle, with Kami being defeated, being pummelled to within an inch of his life.

Krillen is left to take care of Gohan, while Goku and Piccolo easily eliminate the minions, with Goku taking out two, and Piccolo taking one. The two most powerful warriors in the world go in search of Garlic Jr, to finish him off. They find him, and rough him up a fair bit, teaming up well even though they are bitter enemies. They force the evil one to transform, where the fight evens out a bit, although Goku and Piccolo still have the overall advantage. Eventually, Garlic Jr opens up a portal to another world called the Dead Zone, which will trap whoever goes into it for all eternity. It sucks everything in apart from the Earthlings, who all hold onto some sort of pillar, or object. Gohan is no where to be seen though,. Goku and piccolo are about to be sucked in, and trapped forever, when Gohan bursts out of the rocks, and slowly advances on Garlic Jr, somehow nullifying the effects of his attack. He then powers up, and nails Garlic Jr, right into his own Dead Zone, locking him away forever where he shall suffer his eternal life in solitary darkness.
