Sue is an Australian teenager in the late '70s, and her life mainly consists of doing what all the other girls do: watching the surfing boys and having sex with those same surfing boys. The girls have to follow lots of strange customs, e.g. do not eat or go to the bathroom when a boy is around. Ugly girls have two choices - being bitches and hating boys, or being generally cheap and looked down upon by everyone. The afternoons are spent on the beaches, in the backseats of cars, or at home-alone parties where sex and alcohol are the main ingredients. Parents and teachers are trying to straighten the kids out, but it's not easy.
