A volcanic eruption sends the Four-Star Ball flying into the Karin Holy Land, a place protected by Bora and his son Upa. Bora uses his tremendous power to drive back Captain Yellow’s Red Ribbon Army troop, who came in pursuit of the Dragon Ball! However, Yellow takes Upa hostage and demands the Dragon Ball. But Goku happens to pass by, defeats Yellow in a single blow, and saves Upa!! Meanwhile at Red Ribbon Army Headquarters, the world’s greatest assassin Tao Pai-pai shows up, having been summoned by Commander Red!!

After finally managing to return to Red Ribbon Army Headquarters, Blue is killed by a single blow from Tao Pai-pai’s tongue. Tao Pai-pai then sets off for the Karin Holy Land to eliminate Goku! Meanwhile, Goku obtains his heart’s desire, the Four-Star Ball. He also hears the legend of the Super Holy Water, water received from a sage who lives at the top of Karin Tower, and that if drunk will multiply one’s power many times over. Tao Pai-pai then shows up. Bora stands to face him, but before Tao Pai-pai’s fearsome power he is killed in the blink of an eye!! Goku challenges Tao Pai-pai, but?!

Goku is completely helpless before the might of Tao Pai-pai, who is unaffected by even the Kamehameha. Goku is felled after taking a direct hit from Tao Pai-pai’s sure-to-kill Dodonpa! Tao Pai-pai steals the Dragon Balls, and heads to a town to get new clothes to replace his tattered ones. However, Goku survived!! The Four-Star Ball that he had on his breast protected him!! After resolving to use the Dragon Balls to restore Bora to life, Goku climbs Karin Tower in order to become stronger than Tao Pai-pai. However, no matter how far he climbs, he is still unable to see the top.

Goku struggles his way to the top of the tower, and there he meets the cat sage Karin, who has the appearance of a cat. In order to drink the Super Sacred Water that will multiple his power many times over, Goku must actually steal the jar that contains the Super Sacred Water from Karin-sama! Goku pursues Karin-sama with all his might, but is unable to even touch the jar!! Karin-sama says that the only one to have ever drunk the Super Sacred Water was Muten Roshi, 300 years ago. Yet Karin-sama says it took him three years to manage to drink the water!!

After going to retrieve the Four-Star Ball that Karin-sama dropped, Goku makes the round trip up Karin Tower in three hours, even though it took him an entire day when he first climbed up! Furthermore, Goku copies the sleeping Karin-sama‘s breathing and movement during the night, and is then able to read Karin-sama‘s movements and finally obtain the jar of Super Sacred Water. But it contains ordinary water?! It turns out that the act of obtaining the jar was itself training that increased his power many times over!! At that time, having obtained brand new clothes, Tao Pai-pai sets out for the holy land once again.

Arriving in the holy land, Tao Pai-pai attacks Upa in order to learn the location of the Four-Star Ball. Tao Pai-pai loses patience with Upa, who won’t say anything, and tries to kill him, but that’s when Goku comes running in! Goku and Tao Pai-pai confront each other once again! This time, the powered up Goku has a firm advantage!! After realizing that Goku has obtained more power through the legendary Super Sacred Water, Tao Pai-pai climbs the tower in order to drink the water himself. However, Goku doesn’t try to follow him.

Having climbed Karin Tower, Tao Pai-pai tries to get the Super Sacred Water by threatening Karin-sama. However, Karin-sama successfully tricks Tao Pai-pai, and sends him back to the surface! After descending back to the holy land, Tao Pai-pai unleashes a violent attack, but Goku is unharmed!! Tao Pai-pai turns pale and uses a bomb, but Goku kicks it back and Tao Pai-pai ends up blowing himself away. After gathering the four Dragon Balls, Goku flies off to the Red Ribbon Army Headquarters to gather the remaining ones!!

Using the Dragon Radar that was stolen from Goku, Captain Violet returns to Red Ribbon Army Headquarters with a second Dragon Ball. Commander Red is not aware of Tao Pai-pai’s defeat, and looks on in good humor as the signal from the four Dragon Balls Goku is carrying approach on the radar. Meanwhile, Goku’s friends at Kame House use Bulma’s reconnaissance mecha to learn that Goku’s target is the Red Ribbon Army’s stronghold! In order to rescue Goku, Bulma and the others hurry to the Red Ribbon Army Headquarters in Yamcha’s plane!

Goku’s friends pick up Kuririn, who was out shopping, and head on after Goku. They are all prepared to die. Meanwhile, the Red Ribbon Army realizes that the approaching signal isn’t Tao Pai-pai, and begins a general offensive against Goku! Knocking around missiles and fighter planes, Goku charges into the base, and in the blink of an eye defeats nearly half the soldiers! Commander Red is horrified at Goku’s power, which far surpasses his imagination!!

The Red Ribbon Army is on the brink of annihilation because of Goku. Captain Violet steals the money in the vault and flees! The cornered Commander Red attempts to kill Goku as well as Black. It turns out that Red’s objective was merely to use the Dragon Balls to make himself taller. Having survived, Black kills Red and confronts Goku in the Battle Jacket! Goku is KO’d by the Jacket’s formidable power, and cannot move! A sure-to-kill beam aims for Goku!!

After Goku dodges the beam, Black attempts to use a missile to blow Goku up together with the entire base, but Goku repels this missile! As Black realizes he has no chance to win and tries to run away, Goku settles things with a single blow, and the Battle Jacket explodes! Goku reunites with his friends, who were hiding in the forest preparing their strategy, and even they are amazed at his strength. Only one Dragon Ball remains. However, for some reason the Dragon Radar isn’t picking up its signal.
