Helen Hemel (Carla Juri) is an 18-year-old girl who uses vegetables for masturbation and believes that body hygiene is overrated in our society. She provokes others by saying and doing things most people would not even dare to imagine. She is sexually adventurous and visits a brothel to experience being with another woman.
Helen's parents are divorced and she desperately wishes that they get back together. But her mother (Meret Becker) is depressive, hygiene-obsessed and mentally unstable, and her father (Axel Milburg) is insensitive and seems not to take notice of what people around him think. She also has a quiet, younger brother whom she teases by taking his stuffed bear.
Helen feels alone and unloved in the world. Only her best friend Corinna (Marlen Kruse) makes her feel comfortable. Together they break many of society's taboos.
