Five high school students from different walks of life endure a Saturday detention under a power-hungry principal. The disparate group includes rebel John, princess Claire, outcast Allison, brainy Brian and Andrew, 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.

With the occasion all but overshadowed by her sister's upcoming wedding, angst-ridden Samantha faces her 16th birthday with typical adolescent dread. Samantha pines for studly older boy Jake, but worries that her chastity will be a turnoff for the popular senior. Meanwhile, she must constantly rebuff the affections of nerdy Ted, who is unfortunately the only boy in school who seems to take an interest in her.

Hard-as-nails cop Jake Stone moves in with the Robbersons so he can watch a hitman who has moved in next door. The hitman is one thing, but can he survive the Robberson family?
