Watch From the Dark (2009) Official Trailer

6 Girls, 3 Guys, 1 Cabin, and a whole lot of Blood...

Eight college friends gather at a remote cabin for an annual weekend of drinking and fun. When a blood-covered teenage girl crashes their party, she unwittingly brings something with her, that transforms every door of the cabin from an exit to an entrance of terror. With no place to go and nowhere to hide, paranoia flares as they wait for certain death that may take everyone of them before the morning comes.
