After playing a pagan ritual on a dare, a group of high school students find themselves trapped in an endless cycle of their worst fears.

The owner of a small-town junkyard offers a cash reward to whomever can kill her uninvited, space-suited alien guest when its spacecraft crash-lands into her barn. Every wacko within 100 miles turns out, and before long, the junkyard is transformed into a war zone of man vs. man vs. machine vs. alien vs. God only knows what.
