Three gang members and an unwilling initiate are driving through the streets of Erie County after dark with their headlights off, planning to prey upon the first unfortunate soul to give a courtesy flash. A mysterious van falls into their trap and they immediately pursue it, planning to murder the driver and all other passengers. When the four finally overtake the vehicle, abandoned in the middle of the road, they discover fresh corpses inside. From there the tables are turned, and they become the prey of a terrifying evil, the likes of which few nightmares have conjured up.
