Tobias (Heiko Pinkowski) and Flasche (Peter Trabner) are friends for life. Since their youth, the two have not been separated from each other for a single day. Tobias is in the prime of his life, has a wife and children. He carries responsibility. And yet he doesn't seem to grow up. With his buddy Flasche, he rocks the discos and parties with young people whose father he could be. The two drink alcohol all night long and lie hungover in bed during the day. But the carefree lightness of youthful existence has long since evaporated. Tobias increasingly falls out with his wife Anika (Christina Große), his three children and his partner Thomas (Thorsten Merten), with whom he has founded an architecture firm. Tobias loses his driver's license, jobs at the office, his love life with his wife and the joy of his children due to alcohol. Finally, he has a car accident that almost costs the lives of his children. Bit by bit, Tobias realizes that his friendship with Flasche is no longer good for him and that it is time to separate and go his own way. But by the time Tobias comes to this realization, it is long too late. Tobias can't get rid of Flasche. So the murderous spiral continues. Until it gets dirty.
