Jule is shocked: her parents are moving and she has to go with them. Things are terrible in her new class at school. Everyone dances to the tune of the self-important bitch Helen. Luckily Mechthild turns up, and the two new students get on marvelously with each other right from the start. Mechthild doesn't think much of the bitchy behavior of the other girls, but unfortunately she doesn't think much of boys, either. "They only cause trouble." But it is precisely in matters of the heart that Jule desperately needs her support. Because Jule is madly in love!
