Description

In 1986, Harry Dunne finally gets his chance to go to regular school. At the same time, Lloyd Christmas has been adopted and exchanged several times until he is finally accepted by the school janitor, Ray. Harry bumps into Lloyd on the way to school, in search for a treasure his mother asked him to find, and as if it were destiny, the two instantly became the best of friends. Lloyd introduces Harry to his friend, Turk, the school bully whose main function in life appears to be making Lloyds life miserable. After putting Lloyd in a trash can, he hoists the two friends up a flagpole.

Meanwhile, the corrupt Principal Collins is searching for a way to get a large amount of money to get a condominium in Waikiki, Hawaii for him and his girlfriend, Ms. Heller, the schools cafeteria lady. Seeing Harry and Lloyd getting hoisted on a flagpole, Principal Collins decide to establish a fake special needs class to swindle $100,000 from a former Special Needs student named Richard Moffit. Obviously, Harry and Lloyd are more than thrilled to help, unaware of the real reason, and thus find themselves signing up people who are special enough for the class. These include a reluctant Turk a teen named Toby who broke his leg and arm in a skateboarding accident—and whom Lloyd believes is a little crippled boy Tobys gorgeous girlfriend, Terri geeky Lewis, whom Harry and Lloyd believe is a centaur after seeing him half-dressed in his horse mascot uniform Cindy, also known as |Ching-Chong, a Chinese exchange student who later becomes Turks girlfriend and Carl, a badly injured football player obsessed with his sport. Ms. Heller becomes the teacher of the fake class and holds it in Rays tool shed.

Jessica Matthews, a headstrong student and reporter for the school paper, is being suspicious of Principal Collins sudden contribution. Jessica invites Harry over to her house for dinner and asks Harry for information. Harry, who thinks that she is flirting with him, turns to Lloyd for courtship tips. A repulsive disaster involving Jessicas bathroom and a melted chocolate bar that looks like feces makes her father freak out, inadvertently directing her attention to Lloyd. Soon, Harry and Lloyd get into a fight over Jessica, without her knowing it, which causes the duo to angrily break off their friendship. Inevitably, the two make amends when Harry and Lloyd realize that they were nothing without each other. They find Principal Collins chest in his office which contains evidence of every scam he and Ms. Heller ever pulled.

The next day, Principal Collins finds his evidence chest missing, and Ms. Heller falsely accuses Jessica of taking it. As a result, Principal Collins prank calls her parents and keeps her at his house overnight in an attempt to interrogate her. Meanwhile, the Special Needs class builds a float of George Washington for the Thanksgiving Parade. However, after Lloyd and Harry discover the evidence in the chest, they change the float to look like Principal Collins instead. After the class discovers his evidence, they agree to use him as the float instead. They also plan on having it pulled by the classs special bus. Before bringing out the float, they call the police. During the parade, the superintendent of the school district has a police detective pose as Richard Moffit, so Principal Collins would take the grant. Eventually, the Special Needs class brings out their float and proves Principal Collins and Ms. Heller as thieves by putting their recordings over loudspeakers, therefore exposing their plot. Before Principal Collins and Ms. Heller escape with the money, they are arrested by the police. Jessica is grateful for Harry and Lloyd and regards them as heroes. However, just like in the original film, the duos advances to Jessica are in vain, as it turns out that Jessica had a boyfriend. He commends Harry and Lloyd for exposing Collins and Hellers plot and rides off with Jessica.

Harry and Lloyd vow never to fight and risk their friendship over a woman, but as they head home, they are approached by Fraida Felcher and her twin sister, Rita in a red Ferrari 308 GTS, who offer to take them to visit a new girls college. After Harry and Lloyd get into another debate over which girl they want, Lloyd declines the offer to settle the debate, and Fraida and Rita furiously drive off, splattering Harry with mud in the process. Jessicas father accidentally hits Harry with his Mercedes, resulting in Harry getting the windshield and hood covered with mud. Jessicas father recognizes Harry and as he frantically thinks his car is covered in feces, Harry and Lloyd casually walk away.
