The House of the Devil 2009

Sam is a pretty college sophomore, so desperate to earn some cash for a deposit on an apartment that she accepts a babysitting job even after she finds out there is no baby. 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.
