A new start, lonely hearts listings, and secret gifts at the police station—and so begins a new installment of this series.

On a boat in the harbor, two teenagers meet by coincidence and under different preconceptions. One is off to meet a mysterious man who she claims is dangerous, while the other says the boat belongs to his father. Meanwhile, a cop on the night shift tries to sell his old van.

When he witnesses the lovely girl he's just met get shot, Elias calls the police, but he doesn't want to give his last name.

Nina and Paul arrive at the scene and find a man's wristwatch near the victim, who is around the same age as Paul's daughter. She still has her wallet, but it looks as if her cell phone has gone missing.

Mirko, an acquaintance of Daniel's, turns up at the police station with a question concerning a "friend of his" who has lost a gun... At the crime scene, two detectives make it clear to the other officers that they will now be taking over the investigation.

Dirk Matthies is still puzzled as to where Elias got his cell phone number. The detectives from the homicide squad come to his office to ask about it and their conversation is not exactly amiable.

With the help of surveillance camera footage, the officers from the 14th precinct discover that someone rode the victim's bicycle and then got on a train. Of course, this is Elias, the young man Dirk is trying to protect.

After a photo of Elias is released, Dirk has to try to find him however possible. Meanwhile, Nina and Paul try to take care of the financial issues they are each having.

The young suspect is spotted riding a woman's bike around town, so the patrol team sets out in pursuit, as do the homicide investigators. It's clear that the two teams really don't get along.

Mr. Krabbe gives his boss a teddy bear, and Dirk gives Paul some friendly advice on letting go...

Mirko tells Daniel that Lea Stolze, the murder victim, was his ex-girlfriend. And now his gun has gone missing too... How will Daniel react?

Mads give Harry a pep talk before her date. Dirk Matthies receives a phone call from Elias and ends up finding out who Lena Stolz's murderer really is.

Part two of "Der gute Bulle" ("The Good Cop") begins with Dirk Matthies reflecting on everything that has happened so far. Dirk tries to get in touch with Elias, while Nina and Daniel decide to question Mirko.

Frau Küppers considers that Dirk might be trying to protect Elias because of guilt he is feeling related to another case. Meanwhile, Paul is no closer to selling his van, and Elias still hasn't reached out for help.

Nina and her colleague Daniel ask Mirko whether he has contacted the criminal investigation department as promised. Harry Möller tells her colleague about the date she went on the previous evening, and Hannes overhears his chief officer, Frau Küppers, with whom he is secretly in love, talking about her dreams...
