What seems like a game at the beginning soon turns into bloody seriousness.

Day in, day out, Niklas ‘Nick’ Tschiller and his partner Yalcin Gümer investigate crimes that are happening in Hamburg. But at some point even the policeman needs a break to spend time with his daughter Lenny. Then it says: Tschiller a.D. - out of service - goodbye to Hamburg. However, simply relaxing is easier said than done, because crime never sleeps and a new, very personal case throws a spanner in the works for Nick's plans for a well-deserved break. Even on vacation, the criminal investigator is not sure about his job and so a wild journey soon takes him across Europe, including to Istanbul and Moscow.

In rural Westphalia, Franz Berger struggles to keep his inn open. On this day, a bluff, overbearing bully, Hermann Walzer, has booked the dining room for a wedding banquet for his son Mark. There's bad blood between Berger and Walzer, so when the first course, shrimp cocktail, is off, Hermann storms out with the wedding party vowing not to pay. Franz locks the loo door, taking prisoners of the bride and Hermann's wife while he also locks the estate's outer gates, leaving Hermann and the rest outside. Walzer, a pheasant hunter, lays siege; shotguns, rifles, grenades, a shovel, and other weapons leave no one safe. Will it take death to bring these men to their senses?

A kidnapping case starts a dangerous game of cat and mouse for Berlin detective Martin Brühl in the world of illegal car racing. 19-year-old Tim Jatzkowski doesn't come home. At first this is nothing to worry about. But then his father, luxury car dealer Heiner Jatzkowski, receives a ransom demand. Martin Brühl and his team encounter a shocked mother and a rather shirt-sleeved father who thinks the police should do their job and find Tim. The detective tries to convince Jatzkowski to pay the ransom. Among Jatzkowski's regular customers, whom he supplies with tuned luxury sports cars, there are plenty with contacts to the Berlin clans. He decides against paying the ransom.
