The villains of the Kids Next Door, led by Benedict Uno, join forces to resurrect the Ultimate Evil, Grandfather, a tyrant who once ruled the world many years ago when most of the villains were themselves kids. However, Father disgraced him that he can't even try to destroy the KND and the Villains were quickly betrayed when they are turned into Senior Citizombies, creatures that are immortal and can transform any living creature into one of them and slaves who are forced to make Tapioca to refuel Grandfather so he can find and destroy the Book of K.N.D. Once the Villains were zombified, Grandfather unleashes his wrath on the world, transforming every young into old, turning the tree houses into tapioca factories, and the Kids Next Door rallies in defence, but were quickly overrun and zombified. Numbuh 1 is the only surviving KND operative to locate the KND's only hope for salvation, the legendary hero Numbuh 0. In the process, Numbuh 1 discovers shocking revelations about the KND, his arch-enemies Father and the Delightful Children From Down The Lane, and even his own family history.
