Nadine, a young woman struggling with drug addiction and working as a prostitute, finds herself abandoned, mistreated by the police, and battling withdrawal symptoms. In desperation, she returns to her childhood home and the mother she once fled from. Her mother, Delilah, is a devout Christian who believes her daughter’s erratic behavior is due to demonic possession. In her quest to “cure” Nadine, Delilah enlists the help of a rogue preacher who offers to perform an exorcism for a price. Unbeknownst to both women, this decision invites malevolent forces into their lives. As Delilah turns a blind eye to the strange rituals taking place in her home, Nadine, overwhelmed by mental and physical anguish, is forced to endure the preacher’s increasingly violent antics.
