Back then, your best friend was killed - now you are hunting his murderer. Summer 1986: A group of friends from Cologne spends a party weekend in a cabin in the Bergisches Land. For two days, there’s beer, music, a quarry lake, and flirts. By the end, two young people are dead - the girl raped and stabbed, the boy brutally beaten to death. The double murder is never solved. Years later, Cologne newspaper editor Jan Römer is tasked with writing about the unsolved case. Römer remembers it well, as that weekend in the woods marked the end of his youth - he was part of that group. Together with his best friend Mütze, he wants to find out what really happened back then. Too late, he realizes the danger he is putting himself in... "One of those books that keeps you reading all night to find out how it ends. And afterwards, you feel just a little bit cooler because you were part of the '80s.".
