The students of East Great Falls High have spent a year apart, going to different colleges and learning a bit more about life. Jim has discovered that losing your virginity doesn't necessarily make you suave, while Oz is trying to cope with his girlfriend spending a summer abroad. Meanwhile, Stifler remains his badly-behaved self. Coming together for the first time in a year, the guys rent a beach house and vow to make this the best summer ever. As it turns out, whether that will happen or not has a lot to do with the girls.
