Season 1

In the small town of Wäldern in the Bergisches Land, young people are mysteriously disappearing. It quickly becomes clear that these are not normal missing persons cases - an ancient danger lurks in a labyrinth beneath the town. Lara Glanz is still looking for her niece Magda, who the police have declared dead. At the same time, in Wäldern she has become a detective of the inexplicable - she is approached by Jochen Rust, whose daughter Merle has disappeared since the flood in the Ahr valley. While his wife wants to declare her dead, he is sure that Merle is alive and asks Lara for help. Despite all her sympathy, she is initially overwhelmed. But then Merle appears out of nowhere, standing dripping wet in her parents' garden. The girl is a different person - she speaks loving words, but moves through her former home as if remotely controlled. Above all, however, Merle seeks Lara's company. It turns out that Lara and her past are themselves part of the strange occurrences in Wäldern. With the help of Dorothea and Rudolf, Lara finds out that her father was a member of a secret society that guarded the portal to the underworld beneath the village of Wäldern. And her adopted sister Greta also seems to be interwoven with the events in the other world, in which Merle has apparently been for the last two years and from which she has returned as a shadow of herself. Lara follows an inspiration and manages to free Merle from all the ghosts: the girl is herself again. And she can report that she also saw Magda in the other world - apparently Lara's niece is there between the worlds. So Lara was right: Magda is alive.

In the small town of Wäldern in the Bergisches Land, young people are mysteriously disappearing. It quickly becomes clear that these are not normal missing persons cases - an ancient danger lurks in a labyrinth beneath the town. The pianist Lara Glanz returns to her hometown of Wäldern shortly after her niece Magda disappears. Lara takes a job as a music teacher and begins to search for the girl on her own in her free time. The circumstances of Magda's disappearance seem increasingly ghostly. Other incidents and residents of the sleepy village also puzzle Lara. 15-year-old Aaron Wagner is a new addition to Lara's class. The introverted boy's mother seeks Lara's help. She is strangely worried that her divorced husband is forcing the boy to perform strange rituals. Lara takes on the matter and quickly finds herself confronted with forces that cannot come from this world. Lara finds allies in the esoterically gifted alternative practitioner Dorothea Freiberg (Sabine Vitua) and the emeritus professor Rudolf Klein (Peter Franke). At first the three have no idea what demons they have to face, but then it becomes clear: Lara herself plays a central role in this mystery.
