Five high school students from different walks of life endure a Saturday detention under a power-hungry principal (Paul Gleason). The disparate group includes rebel John (Judd Nelson), princess Claire (Molly Ringwald), outcast Allison (Ally Sheedy), brainy Brian (Anthony Michael Hall) and Andrew (Emilio Estevez), the jock. Each has a chance to tell his or her story, making the others see them a little differently -- and when the day ends, they question whether school will ever be the same.
