During a snowy day, Randy shows off his winter clothes to Howard, which includes the Ninja Mask worn inside out as a hood and a red scarf. Howard warns Randy against flaunting his identity carelessly, but Randy claims it doesn't count since he's not actually being the Ninja. However, from a distance away Debbie Kang captures footage of Randy and smiles to herself.
Shortly after, Howard and Randy enter the school when Debbie invites Randy into the Norrisville High Gazette Times Tribune Weekly Daily Press Chronicle Room, where she confronts Randy about his secret identity. Randy tries to brush it off until Debbie shows him her captured footage, featuring him putting on his hood earlier while saying "I'm the Ninja". Randy is unable to come up with an excuse; Debbie, triumphant, declares that she's going to broadcast the news via Heidi Wienermann's afternoon show. In a moment of panic Randy opens the NinjaNomicon in Debbie's face, sending her into the book.
Randy gets Howard out of class and explains the situation. Howard criticizes Randy for inadvertently shoving Debbie into the book, since it's incontrovertible proof that he is the Ninja. Randy quickly destroys Debbie's collection of evidence before asking Howard to guard the unconscious bodies while he goes into the NinjaNomicon himself to get Debbie out. Howard complies, but soon decides to pose Debbie and Randy's bodies in embarrassing positions and leaves.
Inside the book, Debbie correctly guesses that the NinjaNomicon is an 800-year-old compendium of ninja secrets. Randy tries pleading with Debbie to not divulge his secret, but all at once images of armored swordsmen begin surrounding Randy, accusing him of behaving in a way "unbecoming of the ninja" for carelessly revealing his identity. The images chase a fleeing Randy; Debbie casually wonders how to leave the book, which warps her out at her request. As she wakes up, Debbie realizes that Randy has destroyed all her evidence, but decides to bring along the NinjaNomicon as her evidence instead while Randy is unconscious.
Despite Howard's attempts, Debbie declares on Heidi's show that the Ninja is Randy Cunningham; the latter pronouncing Randy's name correctly for the first time. Having been watching the show, McFist sends a robot to the school to hunt Randy down. Randy prepares to go ninja, but realizes that Debbie has taken the NinjaNomicon and his mask along with it, and decides to hide away "until graduation". However, he has a change of heart after hearing the screaming students outside and appears in front of the robot, luring it away and onto the frozen lake. After some effort, Randy manages to sink the robot beneath the thin ice, destroying it.
Randy reappears at school, attempting to deflect Debbie's accusations of him being the Ninja to no success, until Howard appears on the roof of the school with a dummy of the Ninja. Debbie is flabbergasted to see Randy and "the Ninja" standing separately; Heidi angrily tells Debbie off for giving her a mistaken scoop, and the other students leave, disappointed. Randy uses the Ultimate Lesson to mindwipe Debbie permanently, admitting his mistake to the NinjaNomicon and preparing to be mindwiped himself, but the NinjaNomicon praises him for his earlier act of bravery. Randy resolves to treat the secrecy of his identity more seriously as he and Howard get into another brief disagreement.
Debbie wakes up shortly after, unsure of what she's doing until she picks up the note she wrote to herself: "Randy Cunningham is the Ninja". Without any memory of investigating the Ninja, she dismissively tears up the note.
