After Grim is stripped of his powers by the underworld court due to the Boogeyman suing for misuse of his powers (Skarr gets a hole in his body), Grim, Billy, Mandy, and Irwin are set to be exiled, and Numbuh 3 of the Kids Next Door becomes the new Grim Reaper. Boogey's main plan is to steal the Horror’s Hand, an object capable of transforming its holder into the scariest and most powerful being in existence. The group eventually escapes and plans to obtain the hand for themselves for various reasons.

Irwin gets into one of his power trips and again gloats over his wish to make Mandy his queen, but she slap him across the face in refusal.

Both groups eventually reach where the hand is held, and they are forced into a race by Horror, a living statue that cut off its hand, and placed his fears within it. Grim's group wins the race, and they eventually find the hand. Boogey gets a hold of the hand, but he is eventually defeated when he learns that he is not scary. Later on, Boogey suffers from many injuries, and gets a mental disorder, causing him to be afraid of everything around him. Afterwards, Grim gets his job back, and the group learns that they had gotten everything that they wanted without having the hand. In the end, a naked, cut up Billy comes from two weeks in the future to warn that if Mandy had used Horror's Hand, she would have taken over the world in two weeks. He eventually goes back to the future to make sure that things were set right. Later on, the credits roll, and shows epilogues.

After the credits, Billy went back to the future, and finds that Fred Fredburger somehow stole Horror's Hand from Grim's magic trunk and took over the world as the new Lord of Horror. Despite his newly-acquired power, he is very much the same mutant green elephant-like creature he was. He can't spell "Nachos" (he puts a "Z" at the end instead of an "S"), and also revealed his fear was running out of nachos.
