Kevin "Freak" Dillon is a 13-year-old boy suffering from Morquio syndrome and living with his mother Gwen Dillon. He is extremely intelligent and is obsessed with flights of fancy, but due to his disability, he walks with leg braces and crutches. Meanwhile, Maxwell "Max" Kane is a 15-year-old beastly yet good-natured boy suffering from dyslexia and living with his maternal grandparents Susan "Gram" and Elton "Grim" Pinneman. He has flunked the seventh grade twice and is tormented by Tony "Blade" Fowler, a teenage delinquent who is the leader of a teenage bully gang named the "Doghouse Boys". When Kevin is assigned as Max's reading tutor, they form a bond of friendship over the similar circumstances they share, such as both being outcasts in their school and their fathers abandoning them. Freak and Max go to a local festival to watch a firework show where they get attacked by Blade and his gang. The two then escape into a nearby lake with Freak riding on Max's shoulders. Freak later witnesses the "Doghouse Boys" putting someone's purse in a sewer. The two retrieve the purse but are once again confronted by Blade and his gang. They attempt to attack Freak, but Max stops them by picking up a manhole cover and throwing it at the gang, forcing them to flee in a panic. Max and Freak find that the purse belongs to a woman named Loretta Lee. They return the purse to Loretta who is married to Iggy Lee, a former gang leader. Loretta recognizes Max from his childhood; she and Iggy were old friends of Max's father Kenny "Killer" Kane, who is imprisoned for the murder of Max's mother when Max was younger. Afterward, the two boys help each other out with Freak acting as Max's brain and Max acting as Freak's legs by carrying him around everywhere on his shoulders, allowing Freak to partake in activities he couldn't do before such as a basketball game. Now popular among students of the school, Freak, in an attempt to entertain his new friends by playing with his food, chokes on it and collapses. He is then rushed to the hospital where Gwen is informed that Freak has only a year left to live due to his deteriorating health accelerated by the blockage of his airways. One day, Freak shows Max a research center where he is to be rehabilitated. It appears that he knew about his condition as he stated that he'd be the first one to be retrofitted with a new body. On Christmas Eve, Max is kidnapped by Killer Kane who has been released on parole and is taken to Iggy and Loretta's apartment, where he is tied up. Loretta attempts to help Max escape but Killer attempts to strangle her. Max's seeing the attack prompts a repressed memory of Killer Kane killing his mother; he breaks free of his bounds and attacks his own father. Freak tracks Max and Killer Kane to Iggy and Loretta's apartment and breaks in, armed with a squirt gun he claims is loaded with sulfuric acid which he got on Christmas, which he sprays in Killer Kane's eyes. Just before an angered Killer Kane regains himself and attempts to hurt Freak, Max tackles him through the wall where the police are waiting; Killer Kane is then returned to prison for life without the possibility of parole while Freak and Max run home to have Christmas dinner together along with Gwen, Grim and Gram. While exchanging Christmas gifts, Freak gives Max a blank book and tells him to write in it. That night, Freak dies in his sleep due to heart problems in which the next morning Max hears the news from Gram and gives chase to the ambulance on foot. Max recalls the research center Freak had mentioned earlier and rushes there, only to discover that Freak lied: the research center in question is nothing other than a commercial laundromat. Heartbroken, Max breaks down in grief among the laundry workers. The following weeks, Max continues attending school but spends his spare time locked in the basement, even missing Freak's funeral and seeing Gwen moving away. He later runs into Loretta at a bus stop, who advises him that "doing nothing's a drag, kid". He takes this advice to heart and even works up the courage to answer a question from his teacher during a lecture. Inspired by their bond, Max remembers Freak and all the adventures they had so he decides to write it all in the empty book Freak had given him for Christmas. Max gets writer's block on the last page and puts an illustration of King Arthur's grave which reads "Here Lies King Arthur, Once and Future King", to symbolize his belief that he will see Freak again. Max then takes Freak's ornithopter and winds it up, making it fly. As the ornithopter flies off, a narration by Max is heard:
