On a hot summers day two teenage girlfriends skip school and escape boring suburbia by playing a special game: They ride in cars with men and try to humiliate them by using pornographic language. Both feel invincible and think they can always count on each other. Then they meet Horst, a driver who is their equal match, and their harmless game takes a terrible turn as their vulnerability comes to the surface. Suddenly their friendship is exposed to more than it can bear.
