In 1735, Samuel and Deborah Leeds unleashed a horrific abomination upon the world of men. For nearly two hundred years, the legend of the Jersey Devil has haunted the people of Burlington, New Jersey, and the surrounding Pine Barrens. The year is now 1984, and the monster that was released by Samuel Leeds is back. After the horrific deaths of fourteen-year-old Deirdre Cheek and twenty-year-old Harvey Kramer in this quiet, close-knit town, Raef Lorenz, a former priest turned investigator into the supernatural for the Church of Rome, is sent to Burlington to investigate the killings and the reappearance of the Jersey Devil. As the killings and carnage continue, Lorenz uncovers a sinister plot by the demonic offspring of Samuel and Deborah Leeds. With the help of Kerri Wright, the daughter of local sheriff Andy Wright, Lorenz eludes a group of devil-worshipping bikers and fights against satanic assassins on his way to discovering the truth behind the most recent appearance of the creature. Armed only with knowledge, Lorenz becomes caught in the middle of a struggle between heaven and hell with the fate of mankind resting on his shoulders.
