Mary is the child who was saved from drowning in the film's opening scene. Her mother was imprisoned, raped, and tortured by the Mastersons, which resulted in Mary's birth.

She grew up as part of the Mastersons' church, unaware of the true horror of her origins until she learned the family's dark secret.
