Freundinnen & andere monster (1998)

Katja moves with her mother from a small village to Essen. At first she has problems settling into the rough city life, but then she meets the “Fun Gang”, a wild group of girlies. Although Katja succeeds in impressing the four members of the “gang”, the cool “fun gang” has an iron rule: they only accept “real women”. This means that Katja must first lose her virginity.
