The book follows the mischievous antics of two fourth-grade friends who, after hypnotizing their grumpy principal, turn him into Captain Underpants, a superhero of their own comic book creation. The boys navigate through a series of humorous adventures as they control the principal-turned-superhero, who has no actual powers but is convinced of his own heroism. Their escapades are filled with pranks, battles against ridiculous villains, and plenty of toilet humor, all while trying to keep their principal's alter ego a secret and manage the chaos they've unleashed at their elementary school.
