Set in the late 1980s, a satanic cult has a singular focus of unleashing hell on Earth. With the help of an ancient incantation, they conjure a demon, and its members are tasked with feeding it the populous of a nearby small southwestern town.
When the remains of two murdered Princes are discovered at the Tower of London, a troubled Priest must put his beliefs aside to befriend a mysterious prisoner, who has supernatural powers to communicate with the dead. Together they must solve the mystery of who murdered the Princes, as prisoners in the castle dungeon meet their bloody fates at the hands of the Princes' ghosts, who continue to haunt the Castle seeking their revenge.
