Formerly friendly neighbors turn to crazed maniacs. A stranger at a gas station shoves a nozzle down a customer's throat and pulls the trigger. A soaking-wet line of movie-goers smashes its way into a theater to slaughter the people inside. A loving wife attacks her husband, still beating his head against the floor long after he's dead. As the rain falls, blood flows in the gutters -- and terror runs through the streets.
