This simmering Icelandic drama opens with a car accident that leaves brusque, off-duty police chief Ingimundur (Ingvar Sigurðsson) a widower. The plot thickens when, going through his late wife’s possessions, he discovers that she had been having an affair. Despite having close relationships with his remaining family members—specifically his young granddaughter, Salka (Ida Mekkin Hlynsdottir), whose presence provides much-needed levity for both Ingimundur and the audience—the chief becomes obsessed with discovering the truth about his wife and exacting revenge on her affair partner. As a study of grief, writer-director Hlynur Pálmason’s sophomore feature lacks any significant insight, but there’s still something about it that intrigues. It’s slow, but genuinely so, not in any frustratingly self-aware way. It also looks amazing, its eastern Icelandic setting—complete with picturesque mountains, a placid sea, and, in fitting with the film’s title, lots of cloud-like white fog—a sight to behold. Furthermore, Pálmason elevates what might otherwise have been rote art house fare with some earnestly realized nonnarrative techniques. In Icelandic with subtitles.
