THE DEVIL'S RAIN

A curse affects the Preston family, caused by their betrayal of the Satanic priest Jonathan Corbis in colonial New England. Corbis has harassed the Preston family for generations to obtain a book containing the signatures of the members of his cult which bind their souls to Satan. Corbis captures patriarch Steve Preston, who is allowed to escape to warn his wife Emma and son Mark. He tells them to give the book to Corbis, before melting into a waxy substance. Mark advises Emma to keep the book hidden and entrusts her to family friend John. However, moments after he leaves to meet Corbis, he hears Emma scream and returns to find the Satanists have abducted Emma, leaving John bound, hanging by his feet and terrified.

In a ghost town in the desert, Mark challenges Corbis to a battle of faith. Corbis leads Mark to his cult's church where he reveals that Emma has joined them, as reflected by her now eyeless face. When Mark refuses to do the same, he is surrounded and overwhelmed by Corbis's followers.

Sheriff Owens scoffs at John's story of eyeless cultists living in a long-deserted town and refuses to conduct a search for the three missing Prestons, so Mark's older brother, Tom, and his wife Julie search for them on their own. In the ghost town they are attacked by Satanists. After escaping, Tom sends Julie to summon the authorities while he returns to rescue Mark. En route, Julie is captured by a Satanist who was hiding in her car.

Wearing the robe of a defeated Satanist, Tom infiltrates Corbis's church, where Corbis performs a ceremony to convert Mark into one of his eyeless minions. Tom is discovered by the Satanists, but eludes capture. He and Dr. Sam Richards, a psychic researcher, review the book, which explains that the source of Corbis's power is an ornate glass bottle known as "The Devil's Rain", which contains the souls of Corbis's disciples. They also find Mark's signature in the book, which Richards is sure was not there the last time Mark had the book.

Tom and Richards head to Corbis's church and remove The Devil's Rain from its hiding place. The Satanists converge on the church, so Tom and Richards retreat, taking The Devil's Rain but leaving behind the book, which is taken by Corbis. As Corbis begins the ceremony to convert Julie to an eyeless one, Tom jumps in to intervene, and is captured as well. Richards threatens to destroy The Devil's Rain, but is overpowered by the Satanists, and Mark takes the Devil's Rain from him. Richards tells Mark that he can still save his soul by destroying the bottle, while Corbis maintains that if the bottle is destroyed Mark will wander through nothingness for eternity, unable to enter either Heaven or Hell. Mark smashes the bottle. The Devil's Rain is released from the bottle, melting the Satanists (including Mark and Corbis) and burning down the church. Tom and Julie make a hasty exit. As Tom embraces Julie, it is revealed that he is actually embracing Corbis, and that his wife's soul has become trapped within a new Devil's Rain.

Mark smashes the Devil's Rain bottle, releasing the trapped souls and causing the Satanists—including Corbis and Mark—to melt, burning down the church. As Tom and Julie escape, it is revealed Tom is actually Corbis, and Julie's soul is trapped.

The finale unleashes the bottled souls, breaking Corbis’s hold but at a terrible cost: the Preston family is left devastated, and the evil persists through possession. The film closes with a dark twist, suggesting that victory over such ancient evil is neither clean nor complete—souls, once bartered, are not so easily reclaimed.
