When 12-year-old Jonas’ mother leaves to “fight her demons”, he steps up as head of the household, becoming the unofficial guardian to his younger siblings. With food and money running out, the children retreat into a world of their own where, cloaked eerily in black-and-white, their home turns into one of bugs and mysticism – they make saucepan gardens, they take on insects as pets and spiderwebs encroach. Only the friendship of an odd young homeless man gives Jonas hope to survive in an adult’s world.

The ambitious punk rocker Max and the eco-activist Inge cannot stand each other, ever since Max publicly exposed her by singing the offensive song “When Inge is Dancing” in front of the whole school. But for Max and his classmates Fabio, Joscha and Lukas this song in particular has become a real hit at school as well as in the regional music scene: Their band called Systemfehler is on the verge of a breakthrough. But just before the important gig, which could get them a record deal, guitarist Josha is injured and can’t play. Inge happens to be an excellent guitarist, and the only person who can fill in at such short notice. But when Max asks for her help, she imposes one non-negotiable condition: If she decides to play with the band, they will not perform the song “Wenn Inge tanzt”.
