The stately manor house and spacious grounds were once home to the successful businessman Bernd Doppler, his wife Greta, and their son Helge. In 2019, Regina Tiedemann has made her dream come true by transforming the property into the Waldhotel Winden. She's worried, however, that the reports of missing children will stop guests from coming to Winden.
Season 2 : episode 2
The guest in room 8
A man checks in the day after Mikkel Nielsen's disappearance. It is the Stranger, who has to do several things in Winden before closing the passage in the cave. The police only find out about his stay in the summer of 2020, when Clausen and Charlotte Doppler interrogate Regina Tiedemann. At the Stranger's bidding, Regina had also given Jonas the package with Michael Kahnwald's goodbye letter.
Clausen gets a facial composite made of the unknown man and starts a police search. Charlotte is more interested in the collection of images and newspaper clippings the Stranger left behind.
