Olivia Burton, 23, moves to California with her boyfriend — Francis Morales, 24 — against the wishes of their family. Francis’ mother, Lillian, is a devout Catholic who disapproves of her son’s life together and makes her feelings known in the form of violent religious-themed postcards. Despite these objections, the young lovers embark on a new, exciting life together. However, their bliss is cut short after a strange accident that leaves Francis physically and mentally scarred. He soon suffers from night terrors — whispering in his sleep to a figure Olivia cannot see and sleepwalking into strange corners of the house. These episodes frighten Olivia and also suggest that Francis may be hiding something from her. Her investigation leads to a terrifying and perverse discovery; they are haunted by the ghost of Francis’s childhood youth priest — an entity enraged by their cohabitation and come to punish them for their sins.
