Elling, Lona, and Jasper continue discussing the investigation results. Lona has discovered something that justifies a trip to Marnow, where Beck regularly stayed at a specific campsite once a year. Lona and Elling set off, leaving Jasper to conduct further investigations on site.

In an effort to find out more about Beck, Lona and Elling question Mr. Bender, the groundskeeper at the campsite in Marnow.

Lona strikes up a conversation with the campsite owner, Elling receives an unexpected offer from a stranger, and Lona gives Jasper an official order to meet her in Marnow.

Elling meets with the mysterious stranger at a restaurant, where he learns more about Beck's abuse of children. She hands him an envelope containing 20,000 euros, so he now finds himself in a moral dilemma...

When Elling arrives at the campsite in Marnow, he is surprised that Lona and Sören Jasper are already on first-name terms. Elling says that, in his opinion, there is nothing suspicious about Beck's presence at the campsite, which Lona finds puzzling.

Elling seems to notice that something is going on between Lona and Sören Jasper. When Elling visits the forensic pathologist, he learns something there that changes everything.

Meier confronts Elling with the fact that their conversations have been recorded and that he can only prevent his career from being ruined if he hands over the investigation file to her.

Lona confronts Elling about his sudden wealth, and Elling admits that he has accepted a bribe and is now being blackmailed. At first Lona is furious, but she eventually calms down and offers to help.

The money is handed over in the parking garage. Elling and Lona have radio contact, which is fortunate, because everything goes differently than expected...

This crime series is not for the faint of heart. The new episode of The Dead of Marnow begins with a summary of previous events and ends with a wild car chase.

The chase continues and ends in a terrible accident. Lona then returns the rental car and Elling picks her up, having escaped without being seen.

Elling and his wife finally get a moment alone together, though he won't tell her what has happened. Meanwhile, Lona arrives at the campsite, where Jasper is already waiting for her.

When Lona arrives at the campsite, Jasper is still in the trailer. Lona sends him home. She seems melancholic, even the next day when she goes out on the lake alone.

Elling receives a voice message from Hans-Georg, whom he has commissioned to investigate his wife. The content is anything but reassuring! A little later, he is traveling with Lona on a country road and inquires where she has hidden the money.

Air travel has been the focus of much scrutiny lately due to its devastating effects on the environment. How will the aircraft of the future address this problem?
