14-year old Em likes to hang around in her old play house. One day a boy, Jakob, sets fire to it, and Em catches a brief glimpse of him before he disappears. They meet again a few days later. For the first time in her life, Em falls in love.

While her parents are absent, Isabell has invited a few of her closest, best-behaving friends to celebrate New Year's Eve in her house. However, the good spirit turns sour when some older guys crash the party. The alcohol they bring put the teens in a frenzied state where friends become enemies, couples cheat on each other and medical student Peter is almost killed in a party they won't easily forget.
