The Virgin Spring - Jungfrukällan (1960)

Set in beautiful 14th century Sweden, it is the sombre, powerful fable of peasant parents whose daughter, a young virgin, is brutally raped and murdered by goat herders after her half sister has invoked a pagan curse. By a bizarre twist of fate, the murderers ask for food and shelter from the dead girl's parents, who, discovering the truth about their erstwhile lodgers, exact a chilling revenge.
