Großstadtrevier is a German TV series about a group of police officers who work together in the city of Hamburg.
This episode immediately presents two mysteries at the station: one in the form of a fancy package for the police chief superintendent, and the other in the form of an angry phone call. Dirk and Katja are then called to a local company, where a man is refusing to leave his desk despite having retired.

In this segment, we see how the churned butter is put into a traditional wooden mold, take a look at some more farm animals, and catch a glimpse of the "Daberklamm," an alpine gorge.

This episode comes with spectacular views on Austrian lakes and introduces the daffodil festival in Grundlsee.

The segment features more footage of the alpine black grouse, as well as a festival held by the local religious community in the valley of Kals.

As spring struggles to break through, blooming flowers may be preserved in ice. Meanwhile, the male grouse tries to attract potential mates.

Both perpetrators are caught in their respective crimes in this final segment, allowing Katja and Nicki to move on with their lives.

Oskar and Yvonne declare their love for each other, while Danuta, Tom, and Vilo look on. We see that Tom later on becomes a famous writer, with Danuta as his ghostwriter and Vilo as his agent.

When the autopsy records reveal that Katja's father couldn't have killed himself, the group realizes it is time to go after the murderer. Meanwhile, Nicki learns that her father is deceiving her.

Oskar's brother comes home to a terrible scene: his uncle dead, and Yvonne's mother unconscious. Meanwhile, Yvonne reads Oskar's letter.

As they consider destroying the murder weapon, Lothar, Ben, and Katja go back to the scene of Katja's father's death.

In heaven, Oskar learns that it's his uncle who is dying and not him, and that he might get another chance at life.

While Katja deals with the terrible news about her father's death, Lothar argues with Joe about how the situation was handled.

People living in the Alps are also anxiously awaiting spring. The Imster Schemenlauf is a traditional parade to drive out the winter.

Oskar fights with Danuta about who is responsible for Yvonne's breakdown. Danuta thinks she has found her lost bottle of medicine, but it's not hers.

Joe tells Katja that her father actually committed suicide. The others back at the station are unable to find out any information about what happened to the weapon that night.
