It is the 16th century. The Catholic Church has expanded throughout the new continent, Nueva Espana. New monasteries are being built, but the missionaries’ Holy cities are threatened by forces unknown: the earth shakes, buildings collapse, nothing is spared. The devout seek protection by strengthening their faith, some even willing to sacrifice themselves. One hundred years later, poverty forces young Angelica into God’s service against her will. Rebellious, Angelica tries to escape into the outside world, closed behind the convent’s doors, sealed by her vows. As punishment, Angelica is confined to her cell where she is haunted by the spirit of Sister Luciana. The ghost, a nun entombed one hundred years in the convent walls, compels Angelica to free her trapped soul. To release Luciana, Angelica must persuade the nuns to leave the convent and pray in the open, but to leave the cloister is expressly forbidden. Unable to convince her superiors that her visions are nothing more than another attempt at escape, Angelica resigns herself to her destiny.
