An Irish-Canadian gothic thriller directed by Mary Harron (American Psycho) based on a novel by the same name by Rachel Klein. The film was shown Out of Competition at the 68th Venice International Film Festival.
Starring Sarah Bolger, Lily Cole, Sarah Gadon and Scott Speedman, the film tells the story of Rebecca (Bolger), a young girl who, haunted by her father’s suicide. She enrolls in an elite boarding school for girls and, before long, Rebecca’s friendship with the popular Lucy (Gadon) is shattered by the arrival of a dark and mysterious new student named Ernessa (Cole). Lucy falls under Ernessa’s spell and becomes emotionally and physically consumed by her glamorous new friend. Rebecca, whose overtures of concern are rejected by Lucy, finds herself lost and confused. She begins to develop a crush on her handsome English teacher, Mr. Davies (Speedman) and immerses herself in the Gothic vampire novel Carilla for his class. Rebecca starts to suspect that Ernessa is a vampire, but, despite the suspicious deaths that begin to occur, her fears are treated as simple girlish jealousy. As the bodies of young girls pile up and the line between reality and the supernatural starts to blur, Rebecca decides to take matters into her own hands and get rid of Ernessa. Who can say what is real and what is unreal to the heart consumed by passion and a mind afire with loss?
