Mysterion begins on an early-morning bus ride, as we follow a haunted young woman, Külliki Rannu, on her way to Puhtitsa, a Russian Orthodox convent located in a polluted corner of northeastern Estonia. Life at Puhtitsa is filled with backbreaking labor, as women of all ages shear sheep, till the land, make clothes, and build gigantic stacks of firewood. But they also find space for prayer. Over the course of this gentle, transfixing film, Külliki and director Pirjo Honkasalo gain the trust of Puhtitsa’s nuns, discovering what they left behind but also what they’ve gained along the way.
