Embla Nyström has been plagued by chronic nightmares and racing thoughts ever since she can remember. She has learned to channel most of her anxious energy into her position as Detective Inspector in the mobile unit in Gothenburg, Sweden, and into sports. A talented hunter and prize-winning Nordic welterweight, she is glad to be taking a vacation from her high-stress job to attend the annual moose hunt with her family and friends. But a string of unsettling incidents culminate in the disappearance of two hunters. Embla takes charge of the search, and they soon find one of the missing men floating face down in the nearby lake. With the help of local reinforcements, Embla delves into the dark pasts of her fellow hunters in search of a killer.

Under the heartless vault of Greenland's arctic sky, the body of a girl is discovered. Half-naked and tied up, buried hundreds of miles from any signs of life, she has lain alone for 25 years. When Detective Chief Superintendent Konrad Simonsen is flown in to investigate this horrific murder and he sees how she was attacked, it triggers a dark memory and he realizes this was not the killer's only victim. As Simonsen's team works to discover evidence that has long since been buried, they unearth truths that certain people would prefer stayed forgotten.
