When the shotgun-blasted body of a goose hunter is discovered, the police believe they have a list of suspects who may have wanted the victim dead, from his young wife to the caretaker of his property. But then a second body, another hunter, is found with a similar fatal wound. And then a third. As the pattern emerges—all goose hunters, all shot at the break of dawn—Reykjavik policemen Gunnar and Birkir face the terrifying possibility that a serial killer is stalking the idyllic Icelandic countryside.

Gunnar and Birkir set a trap for the one they call “the Gander,” but it quickly becomes a wild goose chase as the murderer plays some tricks of his own. With the clock running out and the discovery of another body all but guaranteed, the cops must determine if there is a thread connecting the victims or if the killings are all part of a twisted game.
