Just-graduated buddies Thilo, Jannek and Gordon Gremberg get drunk and high from a 'mystery cocktail' in a Cologne nightclub. Next morning Thilo's corpse lies by the road, after a beating and fatal fall. Gordon is on intensive care for his OD trip, with a broken foot having jumped off the Mülheimer bridge. Jannek's mother hesitates letting the cops question him in bed, apparently believing his bones all disappeared, but he's taken to the precinct to indicate where the knaves could have bought the drugs or be spiked. Edwin and Günter are surprised that intern Hui Ko, who knows much more about such poison, refuses to go undercover in the club, even more why, but even they prove good bait for the dealers, yet that's not the whole story.
