In the isolated depths of rural Iceland, a childless couple, Maria and Ingvar, make an alarming discovery one day in their sheep barn: a newborn unlike anything they've seen before. They decide to raise the girl, Ada, as their own, but sinister forces — including one very p***ed-off ewe — seem determined to return Ada to the wilderness that birthed her. The masterful and terrifying debut feature from director Valdimar Jóhannsson, Lamb excavates primal fears — of parenting, loss, and the vast and merciless wild — in a dark and unnatural folktale for the ages.
