Both preppy and rebel siblings get detention when their teacher, Mr. Daniel, catches Paris White and her stepbrother Nade cheating off Ava and Nick during standardized testing. After their teacher gives them a speech about how much trouble they’re in, he takes their phones and locks them in the detention classroom while he runs some quick errands. Unfortunately, the teacher forgets about them and they end up being locked in overnight. Bored, locked, and with nothing to do, Ava, Paris, Nade, and Nick start a series of challenges that end up in a nasty fuckfest.
