Andri was too late to save Mayor Hafdis from being kidnapped and now she is in the Hammer of Thor group's clutches. And after leading police on a wild goose chase, Skuli has at last been found, but he is in no condition to talk to police. Could exposure have done this to him or did something else happen out in the wilderness? While still no closer to finding Finnur's killer, the team must use what little information they have to save Hafdis.

Ketill has been finding dead animals up by the lake and has his own suspicions about why Skuli became so ill when he was hiding out in the mountains. Ebo is beginning to feel in danger at the plant – his foreman knows what he's been up to with Vikingur and does not have Ebo's best interests at heart. Thorhildur is still taking impetuous risks and keeping secrets; when Andri discovers the full extent of her youthful indiscretions there are consequences she has failed to consider.
