Mr. and Mrs. Ulman are the older couple who lure Sam out to their creeky Victorian mansion deep in the woods, just in time for a total lunar eclipse. Megan is Sam’s best friend, who gives her a ride out to the house, and reluctantly leaves her there despite suspecting that something is amiss. Victor at first seems like just a creepy guy lurking around the house, but quickly makes it clear that Sam will end this night in a bloody fight for her life
