Kai has wealthy parents, lives in a large villa, and has plenty of time on his hands. So it's not so bad that nobody really notices him at school and his relatives are a little too crazy for him. But within one summer, everything changes. While his parents send him and his cousin on a big bike tour, the two actually end up separating. Back home in Berlin, his dad kicks Kai and his mom out of the house. No father, no money, and no mansion. Luckily, Kai meets the craziest people over the summer, who drag him from one mess to the next and don't give him enough time to mope around.
