It is 1971, and the sisters of the Adoration monastery lead quiet, insulated lives in a remote town in Rizal. Mother Superior Ruth leads the group in its prayers and daily rituals and prides herself in keeping the nuns removed from the vices and vicissitudes of the outside world. Young and fairly new, Lourdes, joins the monastery and gets introduced to the cloistered life. One afternoon, the meeting in town that Remy and Lourdes attend ends well into the evening. On their way back, deep in the woods leading back to the monastery, they fall victim to violence. Devastated, Ruth, Remy and Lourdes individually grapple with the emotional aftermath. Ruth is well aware that the crisis could either destroy the nuns beyond repair or draw them closer together.
