In a northern Alaskan community where once a year the sun sets for 30 days, vampires attack in a feeding frenzy.
Sheriff Eben Oleman is dispatched to handle a rowdy and mysterious stranger in the town. The stranger speaks cryptically of an invasion by a terrifying evil. Shortly, the town goes dark. The electricity and communications are cut suddenly. Strangers arrive and the killing begins. Eben and the other survivors fight for their lives in hopes that the sunlight will bring salvation.
