Episode list

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.

After the police jubilee party, chief Plocher and state attorney Wagenknecht arrive in the underground parking lot, where they find a shot corpse and commend the prompt handling by commissioner Feller, who leaves to bring the bagged evidence to the lab. When detectives Edwin Bremer and Günter Hoffmann arrive, they realize there is no cop Feller so the brass probably let the culprit clear his murder scene and are charged with clearing the case discretely. Victim Dr. Oliver Körfer is also the psychotherapist of Heidrun, Günter's wife, and she demands his 'obvious innocence' proven, while he hopes to cover up that link.

Dodgy lawyer Milz sees no other way to prevent his crime baron client being convicted for murder then disposing of the key witness, Karla Neuhaus, but she's under police protection in a safe-house. So he calls his marker on gambling-indebted prosecution officer Hanno to see the protection is declared compromised and leak the new location, Milz can then arrange a killer. Thus Karla is transferred and given new protectors: pensioner cops Edwin and Günter, who soon smell a rat. While they ask Hui Ko and Zdams to look into the referral, killer Thomas is hired to attack Edwin, Günter and Karla Neuhaus, but his first tempt fails.
