Output: In 1962, Faber College freshmen Lawrence Larry Kroger and Kent Dorfman seek to join a fraternity. Finding themselves out of place at the prestigious Omega Theta Pi houses party, they visit the slovenly Delta Tau Chi house next door, where Kent is a legacy who cannot be rejected due to his brother having been a member. John Bluto Blutarsky welcomes them claiming they need the dues, and they meet other Deltas including biker Daniel Simpson DDay Day, chapter president Robert Hoover, ladies man Eric Otter Stratton, and Otters best friend Donald Boon Schoenstein, whose girlfriend Katy is constantly pressuring him to stop drinking with the Deltas and do something with his life. Larry and Kent are invited to pledge and given the fraternity names Pinto and Flounder respectively, by Bluto, Deltas sergeantatarms. College Dean Vernon Wormer wants to remove the Deltas, who are already on probation, so he invokes his emergency authority and places the fraternity on doublesecret probation due to various campus conduct violations and their abysmal academic standing. He directs the cleancut, smug Omega president Greg Marmalard to find a way for him to remove the Deltas from campus. Various incidents, including the prankrelated accidental death of a horse belonging to Omega member and ROTC cadet commander Douglas Neidermeyer, and an attempt by Otter to date Marmalards girlfriend further increase the Deans and the Omegas animosity toward the Deltas. Bluto and DDay steal the answers to an upcoming test from the trash, not realizing that the Omegas have planted a fake set of answers for them to find. The Deltas fail the exam, and their gradepoint averages fall so low that Wormer tells them he needs only one more incident to revoke their charter. To cheer themselves up, the Deltas organize a toga party and bring in Otis Day and the Knights to provide live music. Wormers wife attends at Otters invitation and has sex with him. Pinto hooks up with Clorette, a girl he met at the supermarket. They make out, but dont have sex because she passes out drunk. Pinto takes her home in a shopping cart and later discovers that she is the mayors daughter. Outraged by his wifes escapades and the mayors threat of personal violence, Wormer organizes a kangaroo court and revokes Deltas charter. To take their minds off this action, Otter, Boon, Flounder, and Pinto go on a road trip. Otter is successful in picking up four young women from Emily Dickinson College as dates for himself and his Delta brothers. He elicits sympathy by posing as the fiance of a young woman at the college who died in a recent kiln explosion. They stop at a roadhouse bar where Days band is performing, not realizing it has an exclusively AfricanAmerican clientele. A couple of hulking patrons intimidate the Deltas and they quickly exit, smashing up Flounders borrowed car and leaving their dates behind. Marmalard and other Omegas lure Otter to a motel and beat him up, believing that Otter is having an affair with Marmalards girlfriend, Mandy. The Deltas midterm grades are so poor that an ecstatic Wormer expels them all, having already notified their local draft boards that they are now eligible for military service. The news shocks Flounder so badly that he vomits on Wormer. The Deltas are despondent, but Bluto rallies them with an impassioned, if historically inaccurate, speech Was it over when the Germans bombed Pearl Harbor? Hell no!, and so they decide to take action against Wormer, the Omegas, and the college. They convert Flounders damaged car into an armored vehicle and hide it inside a cakeshaped breakaway float in order to sneak into the annual homecoming parade. As they wreak havoc on the event, the futures of several of the student main characters are revealed using freezeframe labels. Most of the Deltas become respectable professionals, while their adversaries suffer less fortunate outcomes.
