Enno Redenius is found murdered in his yard. For the Leeran police, the question arises as to who might be interested in the death of the founder of a citizens' initiative. The initiative is against increasing the holiday home quota and for affordable housing in the region. The protests seem to be a thorn in the side of the up-and-coming member of the state parliament Imke Claasen. Both her assistant Luis and her mother Henriette suffer from Imke's moods. After Redenius ' death, the young activist Nele Hinrichs takes over the leadership of the citizens' initiative. As the police officers Süher Özlügül and Henk Cassens find out, she did not always agree with the founder of the group. With his granddaughter Tina, Enno Redenius was apparently also in the permanent clinch.
And even a farmer Dirk Poppinga, the victim's neighbor, does not seem to be well talking about him due to past events. The numerous suspects puzzled Chief Criminal Commissioner Brockhorst and his two police officers. It is very convenient for them that pharmacist Insa Scherzinger can give valuable information about a possible instrument of action based on the victim's injuries. Meanwhile, undertaker Wolfgang Habedank is targeted by an unscrupulous architect who wants to make an immoral deal with him in order to get explosive information about potential holiday properties. Süher's brother Yunus is also in the Bredouille because the house in which he lives for rent is to be converted into such a holiday home. That is why he is desperately looking for a new place to stay.

While the police in Leer are confronted with an unknown dead man on the beach, Yunus surprises his buddy, undertaker Wolfgang Habedank, with an unusual business idea. To finance the new business model, Yunus asks his sister, patrol officer Süher Özlügül, for the necessary start-up capital. Süher is not very enthusiastic about it. She also has to take care of the body found on the beach with her colleague Henk Cassens. Surprisingly, this time Chief Inspector Jan Brockhorst gave the two patrol officers an unusually free hand in the investigation. Because what nobody suspects at first: The chief of police personally gave him onetransfer proposed. And Brockhorst doesn't want to miss this opportunity. Pharmacist Insa Scherzinger is stressed out by the annual inventory.
So Süher and Henk are just what you need. Insa is tasked with examining the victim's shoe to find out more about the dead man's identity. And indeed, she soon makes an important discovery, which leads the two police officers to the clearance specialist Hilko Wetzlaff. Pharmacy employee Melanie Harms should meanwhile continue to take care of the inventory. And contrary to expectations, Melanie is actually enthusiastic about the cleansing effect of her new job.
