Dr. Hartmann summons the investigators to a refrigerated truck. After 15 years, the Blaueis Glacier has released Vroni Gagern's body. Because Jerry immediately notices that the safety rope has been cut, and because rumors have been circulating about the Gagerns' marriage, the police reopen the investigation. Soon, not only is widower Hannes a suspect, because he had an argument with his wife before her last mountain tour, but Eric Wolters, a physiotherapist, also falls under suspicion for medical malpractice. And what is Sebastian Niederegger hiding, whose wife Julia is currently pregnant? While searching for remains on the glacier, Veronika's son Moritz finds his mother's backpack and could shed light on the mystery.

On her way to the Röder law firm in Berchtesgaden, Munich businesswoman Paola Wagner crashes her convertible on a mountain pass. She was attacked by a drone. When Sophia and Jerry visit the lawyer, Wagner's business partner, Sven Mielow, is waiting for her. He admits to having been in a relationship with Paola in the past and to having been surprised by her desire to leave their joint company.
