After a janitorial mishap, an unsuspecting custodian transforms into Janemba, a fat, yellow demon who wreaks havoc throughout the afterlife. Gokuu Son has been competing in martial arts tournaments for the undead since his heroic death in the battle against Cell. Soon, Janemba's chaos draws Gokuu and fellow combatant Pikkon toward him, forcing the pair to figure out a way to defeat the giant monster.

After a bout with him, Gokuu witnesses Janemba undergo another transformation: the demon sheds his fat and changes color, turning into a sword-wielding enemy more powerful than anyone Gokuu has faced thus far. With the aid of his similarly deceased rival Vegeta, Gokuu must stop the terrifying Janemba from disrupting the very fabric of the universe.

Earth is finally peaceful again, but this calm is short-lived. The remnants of Frieza's army, led by Sorbet and his right hand Tagoma, arrive on Earth in order to summon Shen Long with the goal of resurrecting their old master. To do so, they threaten Emperor Pilaf, Shuu, and Mai for the Dragon Balls in their possession.

Once successfully revived, Frieza—who had been stoking his hatred for Gokuu Son and Future Trunks in Hell—proclaims that he will not be content until they are dead by his hand. Sorbet informs him that Future Trunks has not been heard of in years, and Gokuu's power has far surpassed even that of the mighty Majin Buu. Unfazed, Frieza responds that he only requires a few months of training before being capable of defeating Gokuu.

Will Frieza be able to exact revenge upon his nemesis, or will Gokuu, Vegeta, and their friends prevail against adversity, saving Earth once more?
