According to IMDB, the film is about a girl who is trapped in her family's lakeside retreat, and begins to descend into a state of madness:
this looks like a cross between Elizabeth Olsen's latest film Martha Marcy May Marlene (which was very juicy and one of PedroDotCom's top flicks of 2011) and some shitty haunted house movie. in other words, I've seen this type of diarrhea one too many times. however, I think Elizabeth is a brilliant young actress, and her sisters are pretty fierce too, so I may just have to check this one out when it hits the big screen.
starring Elizabeth Olsen and no one you've ever heard of.
in theaters March 9 2012.
