On a snowy night in Baltimore, air traffic controller Charley Hudson observes a blip on his radar-vanishing and reappearing, changing altitude at speeds no manmade aircraft could manage. Seventy miles away a God-fearing farmer beholds a flash of light in a vision, ominously hinting of evil to come. Oblivious to these occurrences, young exec Brad Barron begins welcoming guests for a Friday night bash.Grounded by her guardian uncle, beautiful Nanatobi Gray pines away in her bedroom, unaware her best friend Renee Van Cedar has been refused permission to see her. Unable to spend the evening with Nanatobi, Renee decides to attend Brad Barron's party. She leaves Nanatobi's house and drives to Brad's apartment, oblivious to the fact she's being followed by lovesick Ronnie Carr, an ex-marine who's been trying to introduce himself since spotting her at the University of Maryland two months ago. He finally succeeds by pretending it's a coincidence they've come to the same apartment complex, and winds up accompanying her to the party.The mysterious blip finally disappears for good and the city is plunged into darkness. When power is restored Nanatobi and Brad simultaneously experience an uncanny phenomenon-one that besieges them a second time before they finally meet one another. The incidents continue and start to evolve, bringing eerie revelations of betrayal, demons, and death. Ronnie also finds himself wrestling with the paranormal as a bizarre series of events unfold that tests friendships, puts lives at risk, and uncovers the existence of an appalling sex cult, whose leader secretly offers human sacrifices to a pagan deity.
