When Larry and Kent pledge the rowdy Delta Tau Chi fraternity, they find Bluto, Otter, Hoov, D-Day, Boon, and the whole fraternity in the crosshairs of the dean and rival Omega House. As Dean Wormer plots to expel them, the Deltas refuse to go quietly—scheming, partying, and stirring up chaos in a final stand for their house. © 1978 Universal Studios. All Rights Reserved.
