When five high school students from different social groups are forced to spend a Saturday together in detention, they find themselves interacting with and understanding each other for the first time. A jock (Emilio Estevez), a criminal (Judd Nelson), a princess (Molly Ringwald), a basket case (Ally Sheedy), and a brain (Anthony Michael Hall) talk about everything from parental tension to sex to peer pressure to hurtful stereotypes while serving time. Ultimately, the five find that they may have more in common than they ever imagined and learn more about themselves as well as each other. The only question is, Will they remember what they've learned after they leave detention
