Richard is approached by The Pagemaster who sends him on a journey into the fiction section to find the "exit". Along the way, Richard befriends three anthropomorphic books: Adventure (Patrick Stewart), a swashbuckling pirate-like book; Fantasy (Whoopi Goldberg), a sassy but caring fairy tale book; and Horror (Frank Welker), a fearful "hunchbook" with a misshapen spine. The three agree to help Richard to find his way out if he checks them out with his library card. Together, the quartet encounter classic-fictional characters. They meet Dr. Jekyll (Leonard Nimoy) in a haunted house where he then turns into Mr. Hyde and terrorizes the group, driving them to the roof where they then head out into open waters to the Land of Adventure. However, the group are separated after an attack by Moby Dick. Richard and Adventure are picked up by the crew of the Hispaniola, captained by Long John Silver (Jim Cummings). The pirates go to Treasure Island, but find no treasure, nearly causing a mutiny between the captain and crew. Fantasy and Horror appear and defeat the pirates. Silver attempts to take Richard with him, but he retreats when Richard threatens him with a sword. Adventure insults Horror, causing the hunchbook to get captured by Lilliputians from Gulliver's Travels. Adventure saves him and they make up.
As the group travels through the fantasy section, Richard sees the exit sign on the top of a mountain. However, a sleeping dragon is awakened and chases Richard and his friends. Richard fights the dragon off with a sword and shield, but the dragon wraps its tail around him, shaking his armor and weapons off of him before swallowing him whole. Richard finds books in the dragon's stomach and uses a beanstalk to escape, he then jumps and the Dragon bites the beanstalk defeating him. The heroes arrive at the top and enter a large dark room where the Pagemaster awaits them. Richard berates the Pagemaster for the horrors he has suffered, but the Pagemaster reveals that the journey was intended to make Richard face his fears. Dr. Jekyll, Captain Ahab, Long John Silver, and the dragon reappear in a magical twister congratulating him. Richard then awakens, discovering that he had been "unconscious" all along. Adventure, Fantasy, and Horror all appear next to his body as real books. Mr. Dewey finds him, and, even though the library policy only allows a person to check out two books at time, lets him check out all three books "just this once" as Richard may not have been unconscious and may actually have witnessed all the events that happened, thus making Mr. Dewey the Pagemaster. Richard returns home a braver kid, sleeping in his new treehouse. Adventure, Fantasy, and Horror appear as silhouettes on a wall talking.
