IMDB

Ferris (Tatum O'Neal) and Angel (Kristy McNichol), both 15, are the only virgins in their bunk at an all girls camp. The other girls make a bet on which girl will be the first to lose their virginity that summer. Ferris targets an older camp counselor (Armand Assante) and Angel targets a boy from the boys camp across the lake (Matt Dillon).
This movie was excellent. It's got a similar plot to American Pie, but it's played straight and there's no pie fucking. It deals with the sensetive topic of young girls being peer pressured into losing their virginity with grace. While it's played straight and realistically, which is helped by the great acting, there are some laughs.

10/10
