The trailer for one of the most buzzed-about indie films of the year, 'Martha Marcy May Marlene,' has finally arrived, and we're already kind of freaked out. This is a very good thing.

The film stars Elizabeth Olsen, younger sister of Mary-Kate and Ashley, as Martha, a young woman who escapes a cult. She cannot, however, get away from the psychological damage inflicted by her time in the cult and finds it difficult to readjust to society. The film co-stars Sarah Paulson, Hugh Dancy and 'Winter's Bone' Oscar-nominee John Hawkes as the cult leader.

'Martha Marcy May Marlene' scored raves at this year's Sundance Film Festival, earning first-time writer-director Sean Durkin the fest's Best Director prize. Fox Searchlight will release the film on Oct. 7.

Check out the spooky trailer after the jump.
