In this new season, a 41-year-old woman disappears. The investigation reveals she had been watched and harassed for months by someone who forced her to take part in a chilling game of hide-and-seek, punctuated by images, videos, and a nursery-rhyme–like lullaby.
When the victim is found dead, Hess and Thulin uncover a potential link to an unsolved case: the murder of a 17-year-old high school girl two years prior. Season 2 stakeouts the hallmarks of a Scandinavian thriller, with a criminal investigation, a resurfacing past, and a looming threat that could strike again.
Mikkel Boe Følsgaard returns to the role of Mark Hess, alongside Danica Curcic as Naia Thulin. The detective duo remains at the heart of the story, as their professional relationship continues to be complicated. Sofie Gråbøl and Katinka Lærke Petersen are also part of the announced cast.
