Why does Helen Koch commit serious vehicle theft?

Sinopsis Film

Cranky teacher Helen and notorious problem student Mia hate the social roles they were assigned by the institution of highschool. When a seemingly harmless conflict between them escalates, the boundaries of their identity constructs and those of the cinematic narrative are blown. What follows is a genre-busting trip through nocturnal Berlin, driven by a longing for physical immediacy and a worthy sparring partner in an increasingly disembodied and virtual world.
