Arch Stanton has a bad job that's about to get a hell of a lot worse.

He's sixteen, scrawny, and dirt poor. He has an almost supernatural ability with with firearms, but it may not be enough to survive the weekend.

Welcome to Whitewood, an isolated small town in northern California, a place full of bad manners and enough worse hygiene. Money is tight, jobs are scarce, and bitter rivalries have simmered just under the surface for years.

Fat Ernst runs the local bar and grill. He'd stomp on his own mother for a chance at easy money, and when he forces Arch to do some truly dirty work, all hell breaks loose.

Fat Ernst's customers find themselves being infected by vicious, wormlike parasites and dying in unspeakable agony. As events spiral out of control, decades of hatred boil over into three days of rapidly escalating carnage. Will anyone in this town escape... before they're all eaten alive?
