Starring Cynthia Nixon, Matt Dillon, Tatum O' Neal and Armand Assante as a sports coach, the movie is about a group of teenaged girls that go to summer camp and bet on which of them will lose their virginity first. After that, they choose targets, or guys that they want to be the ones they lose the virginity with. The sports coach is one of the guys chosen by one of the girls.
In between, the girls engage in typical teenager acts of fun, such as food fights and other activites.
