Dark Family Tree

In the town of Winden, the family trees of the Kahnwald, Nielsen, Doppler, and Tiedemann families are tangled in a seemingly unbreakable time loop. The core paradox links the Kahnwalds and Nielsens: when Mikkel Nielsen disappears in 2019, he travels to 1986 and is adopted, growing up to become Michael Kahnwald, the father of Jonas Kahnwald. This incestuous connection makes Jonas's love interest, Martha Nielsen, his aunt. The Doppler family contains its own temporal anomaly, as police chief Charlotte Doppler is both the mother and the daughter of her own child, Elisabeth, through a relationship with the priest Noah. The Tiedemann lineage is central to the conspiracy, with Claudia Tiedemann's time-traveling actions and her grandson Bartosz eventually fathering Noah. Ultimately, these interconnected loops are perpetuated by a single origin point: the child of Jonas and an alternate-world Martha, whose descendants create a bootstrap paradox that ensures the families' fates are forever entwined.
