There's a little wild west amusement park in California's high desert. Old Madelyn Ghost Town attracts tourists every weekend. There are all sorts of rides and attractions peppered among the historic buildings. Here, you can take a ride through the Haunted Mine, have an old-fashioned chicken dinner, or watch a Wild West show... And if you camp out, you just might see a UFO or two.

Between the modern town of Madelyn and the historic park, lies the compound of The Prophet's Apostles. They think the lights in the sky have been sent by God to warn of the coming apocalypse. They want to convince and convert everyone they can -- and they'll do so by any means necessary.

As a young serial killer stalks Madelyn, leaving blood-soaked horrors in his wake, the earthquakes begin. A monstrous freak storm pounds the arid desert, and the military harasses an astrophysicist and her assistant as they study the night sky ... Sheep are mutilated. People are flayed. And Prophet James Robert Sinclair realizes that God is truly speaking to him.

The Savior is returning. The Four Horsemen are about to ride. And the Apostles are taking no prisoners.
