Her lifeless body is found along the path through the woods that leads from the train station to the college. The news of his death caused panic among the companions: six months earlier, in fact, another girl had been murdered in similar circumstances. During the investigation, Derrick realizes that Ellen's death is to be connected to the crime that took place some time before and he devises a plan to frame the killer.

The lifeless body of the owner, Martha Balke, is found in a country house.

Meanwhile, Marta's twin sister Johanna returns to Munich from the United States. When Derrick meets her he has an idea that could be helpful in framing the killer.

A heated discussion arises between the two young people because Erich does not want to marry Helga and, on the contrary, tries to buy the girl's silence. The next morning Helga's lifeless body is fished out of a pond.

Along the metropolitan railway between Munich and Ottobrunn, the police find the body of a young woman, the third in a few weeks.

Paul Bubach, a charming middle-aged man, meets older women and convinces them to sell their belongings to move with him to the island of Madeira where they can spend a second youth.

Even Kläre, Bubach's niece, cannot imagine that her beloved uncle could be a murderer. In the absence of any clues, Derrick is forced to wait for something to happen...
