The 15-year-old Kurbel, lives in a village in the Lausitz and feels really grown up. He is tall and strong, tolerates plenty of rhubarb wine and he has already kissed. But with his ingenious new lawn mowing method he causes a forest fire. In a non-adult way he puts himself before his responsibility, which leads to the end of his love for Daniela and makes him an outsider. Luckily, there are also some understanding adults, so that crank can finally say, "Life is complicated, but nice".
