Matthew Cave is a Danish journalist in his late 20s. He has let go of his grip on life day by day after the loss of his girlfriend and their unborn daughter in a traffic accident. The escape from reality has driven him to Nuuk, spurred on by a 20-year-old postcard his American father sent from Thule Base before he disappeared. Matthew is sent to the edge of the ice cap to cover the discovery of a mummified Norse Viking, the first well-preserved Viking ever found. Everything is set up for a world sensation, and the small Arctic community holds its breath. But chaos breaks out when the mummy has disappeared, and an officer is found dismembered and eviscerated. Matthew comes on the trail of four identical murders in 1973, which are connected to the disappearance without a trace of two 11-year-old girls. The two cases flow together for Matthew, and he quickly gets his fingers deep into the bloody murders of both the present and the past. The only one he really dares to trust is a young Greenlandic woman who killed her father as a 14-year-old - by ripping him open and disemboweling him. Her body is covered in tattoos. The skin worn off when she was a child. Her will strong as the mountains around Nuuk.
