Plot:

The movie opens as Numbuh 1 is narrating, we then see massive factories covering the landscape of Britain and child labor widespread. All of this is controlled by an evil old man later known as Grandfather (though referred to as Pappy by his sons). However, one of his sons escapes a factory with his younger brother chasing him. The older brother climbs up a tree, while the younger brother climbs up to him telling him that he can't just run off in the middle of his shift and that "Pappy" will be angry not finding them. But the older brother decides just to let him, stating that they've been slaving away making tapioca for 11,000 days straight, and their father does in sneer at them like he's the evil king of the world (which the little brother emphasizes that he is). The big brother states that he's tired of it and just wishes that they could fight back as he kicks the tree. He wish is granted when he opens a door and stumbles on to a strange chamber, which contains 2x4 Technologyas well as the Book of KND, a legendary book that contains instructions on how to use said technology as well as information recorded by previous KND operatives.

One of the sons plans to use these resources to rebel against Grandfather while the other balks and runs away, stating that they have "zero" chance of defeating their father. The son who stays dons sunglasses similar to Numbuh 1's, declares that he'll show him "what the number zero can do," and leads a revolt, destroying the tapioca factories. However, Grandfather finds out about his rebellion and gives him three seconds to go to his room, or else. With his fists swirling with energy, Grandfather counts down malevolently. But once he reaches one, his son shouts his number and fires a beam at his father, decommissioning him and reverting him to a harmless old man. This leads to the "Seventh Age of the KND" with Numbuh 0 becoming the greatest KND operative of all time. However, as so much time has passed, many regard the story as mere make-believe, though Numbuh One believes the story to be true. The scene suddenly cuts to the present with Numbuh 1 telling the story, claiming that if he ever found the Book of KND, he would write only five words: "I am Kids Next Door". He is then given an order by Numbuh 86 to deliver to the Kids Next Door Seriously Cool Museum of Artifacts and Stuff, a shrine to Numbuh 0 complete with the Recommissioning Module, a device capable of restoring decommissioned agents' memories. Much to Numbuh 1's frustration, his important delivery turns out to be an ice cream cone for its tour guide, Numbuh 101, who is an ultimate fan of Sector V and regularly breaks into Numbuh 1's room.

At the Moonbase, realizing the severity of the situation, Numbuh 2 tells Numbuhs 362, Numbuh 86, Numbuh 3, and Numbuh 4 he has a device at Sector V Treehouse that can help build new Age-o-tonic Birthday Suits that protect them from the Senior Citi-Zombification. Numbuh 3 volunteers herself and Numbuh 4 to get it at the treehouse, meeting up with Tommy Gilligan, who was later turned into a Citi-Zombie by Toiletnator. While attempting to avoid a zombified Numbuh 5, Numbuh 3 is transformed as well. She manages to transform Numbuh 4 by kissing him. As the KND transform one by one, Numbuh 1 quickly becomes hard-pressed to survive as the last active KND member. But with some encouragement from Numbuh 101, Numbuh 1 got up on his feet and decided to track down Numbuh 0, their last chance of hope. The villains point out that he defeated the KND, controls all the world's villains and he has all the tapioca he can eat; Grandfather pushes this off, stating that he must destroy the only thing that could oppose him: the Book of KND before his reign will be permanent. When kids read it, they discover the only thing more powerful than even Grandfather: hope. Grandfather swears that this time, he will destroy the book utterly.

Meanwhile, Numbuh 1 begins to track down Numbuh 0 in hopes of recommissioning him with KND Tracker, finally tracking Numbuh 0 to his very own home, and comes to the shocking realization that his father is Numbuh 0. After entering the Treasure Chamber of Coolness, Numbuh 1 recommissions Numbuh 0 and informs him about Grandfather's plans and the status of the entire world. On the Moonbase, Numbuh 1 and Sector Z manage to defeat the zombified Sector V,, and maneuver the moon to face Earth. Unfortunately, Sector Z revert back to their evil selves and attack Numbuh 1. On Earth, Grandfather acknowledges Numbuh 0's impressive resistance but states that he can't stand against him forever; he stands "zero" of a chance; Numbuh 0 acknowledges this, also stating that his son is Numbuh 1.

At that moment, Numbuh 1 manages to defeat the DCFDTL, sending them to space in a escape pod, but not before the targeting system is destroyed. Numbuh 1 switches to manual targeting, but it requires four other members to operate. However, when Numbuh 1 attempts to Recommission Numbuh 0 once again, it immediately falls apart. He comes across a recorded message from Numbuh 0 telling him that he has destroyed the Recommissioning Module and that he would rather not have his memories restored so that he could complete his greatest mission of all: being a good father to his son. He declares Numbuh 1 keeper of the book and advises him to write new stories in it. One month later, the existence of Numbuh 0 is public knowledge and considered fact. The Moonbase has been completely rebuilt and is larger and better than the previous one. It also now contains a massive statue honoring Numbuh 0. Numbuh 1, who now has possession of the Book of KND, writes his entry into the book. The entry consists of only five words: "We are Kids Next Door." The movie ends with Numbuh 1 revealing the entire (presumably) KND around him.

In a mid-credits scene, the KND are making an another mission while Numbuh 1 decided to go on a journey on his own. In a post-credits scene, The Powerpuff Girls approaches Numbuh 0 and informs him that a team is being put together
