In a remote Icelandic town, Ingimundur (Ingvar Sigurðsson), a recently retired policeman, begins to suspect a local man of having had an affair with his late wife, who died in a tragic accident two years earlier. Gradually his obsession for finding out the truth accumulates and inevitably begins to endanger himself and his loved ones.
