Devout Christians Töre and Märeta send their only daughter, the virginal Karin, and their foster daughter, the unrepentant Ingeri, to deliver candles to a distant church. On their way through the woods, the girls encounter a group of savage goat herders who brutally rape and murder Karin as Ingeri remains hidden. When the killers unwittingly seek refuge in the farmhouse of Töre and Märeta, Töre plots a fitting revenge.
