The Secrets from the Deep

1995: A young German woman disappears in the Westfjords of Iceland, but the case is quickly forgotten. After all, it's not uncommon for foreigners who come to Iceland to vanish, and the police are too busy investigating a fatal car accident, recovering two bodies from the cold waters of the sea. 2022: Detective Hildur Rúnarsdóttir returns from a surfing holiday in Hawaii to a good life.

The renovation of her childhood home is progressing, and her colleague and friend Jakob Johanson has permanently joined her in Iceland. But when Hildur visits her family friend, Helga, in a nursing home, she is presented with surprising new details about her mother, Rakel. Then a cruise ship carrying a large group of tourists arrives in Ísafjörður, bringing a world of trouble with them.

As the bodies pile up, Hildur and Jakob must look to the past to figure out what lies in front of them.
