Rebecca (Sarah Bolger), a young girl haunted by her father's suicide, begins her journey at an elite girls' boarding school. Before long, Rebecca's close friendship with the popular and sunny Lucy (Sarah Gadon), and her sense of safety, are shattered by the arrival of the dark and mysterious Ernessa (Lily Cole).
Lucy quickly falls under the glamourous Ernessa's spell and becomes emotionally and physically consumed by their intense friendship. Rebecca, her overtures of concern and friendship rejected by Lucy, is lost and confused. She soon develops a crush on her handsome English teacher, Mr. Davies (Scott Speedman), immersing herself in the Gothic vampire novel Carmilla that is the subject of his class.
Rebecca starts to suspect that Ernessa is a vampire, but, despite the suspicious deaths that begin to occur and Lucy's wasting away, her fears are treated as simple girlish jealousy. As the the bodies of young girls start to pile up and the line between reality and the supernatural starts to blur, Rebecca decides to take action and get rid of Ernessa.

2012 Guide Analysis: "An Irish-Canadian horror film based on a novel by Rachel Klein, this marks the return of "American Psycho" and "I Shot Andy Warhol" director Mary Harron with a vehicle designed to cash in on the teen female vampire fanbase already being milked by the likes of "Twilight" and "The Vampire Diaries".
The story is set in a boarding school where new arrival Ernessa (Cole) comes between two best friends Rebecca (Bolger) and Lucy (Gadon). As Lucy falls under Ernessa's spell, Rebecca begins to believe Ernessa is a vampire.
Reviews from both Venice and Toronto were not kind, calling it a vulgarly obvious mix of Jane Austen's "Northanger Abbey" and Dario Argento’s "Phenomena". "The Tudors" star Bolger scored good notices, and the oddly ethereal looking Cole seems well cast as a vamp.
Harron was targeted for the most criticism though, such as bringing up numerous interesting threads and then dropping them, or making the supernatural elements obvious when something more psychological and dubious in nature would've been a better fit.
Still, it's the kind of film that has cult hit stamped all over it, so much so that IFC has picked it up for distribution and will likely get good play out of it on the home video circuit after a limited theatrical run."
