The Roost

Synopsis: A group of young people are en route to a friend's wedding in the remote countryside of Pennsylvania when they hit something unseen, lose control of their car and become stranded. The foursome reluctantly wanders down the deserted road and into the eerie darkness. They come upon a farmhouse where they hope they can use the phone to call for help -- but no one seems to be at home. It isn't long before they learn that the farm has been taken over by vampire bats that have already claimed the lives of the older couple who lived there. But, once bitten, the victims come back to life zombie-style and those still living have to not only dodge the bats, but the undead as well.     Source: RottenTomatoes.com
