Plot: Five teenagers head off for a weekend at a secluded cabin in the woods. They arrive to find they are quite isolated with no means of communicating with the outside world. When the cellar door flings itself open, they of course go down to investigate. They find an odd assortment of relics and curios, but when one of the women, Dana, reads from a book, she awakens a family of deadly zombie killers. However, there's far more going on than meets the eye.
Alternative Plot: When five college friends (Kristen Connolly, Chris Hemsworth, Anna Hutchison, Fran Kranz, Jesse Williams) arrive at a remote forest cabin for a little vacation, little do they expect the horrors that await them. One by one, the youths fall victim to backwoods zombies, but there is another factor at play. Two scientists (Richard Jenkins, Bradley Whitford) are manipulating the ghoulish goings-on, but even as the body count rises, there is yet more at work than meets the eye.
