Mother in rehab, father on a business trip with his assistant: Maik Klingenberg will spend the summer holidays alone at the poolside of the parental Villa. But then Tschick turns up. Tschick, whose real name is Andrej Tschichatschow, actually comes from one of the high-rise buildings in the socially disadvantaged Hellersdorf, has somehow managed to make it from a school for children with learning difficulties to grammar school but does not really look like the perfect example of integration. He also has a stolen car at hand. And so begins a journey without a map and compass through the German province in the blazing hot, unforgettable just like the river trip of Tom Sawyer and Huck Finn.
