On a remote island, three Catholic nuns are the last remaining members of the enclosed order of St. Agnes. Forgotten by the rest of the world, they live in a dilapidated monastery, where wild vegetation grows out of stone angels, and sheep wander freely through the chapel. The nuns live a humble life of work, prayers, and telling dark fairy tales as they knit until an ambitious young priest arrives on a mission from the church. When the nuns become aware of Father Ignatius’ true intentions, they are forced to take matters into their own hands. What unfolds is an epic and fantastical tale of faith, love and redemption.
