The Moth Diaries

“Every girl has her secrets.”

Rebecca (Sarah Bolger) is still grieving her father's suicide when she enrolls at an elite boarding school for girls, where her friendship with the popular Lucy (Sarah Gadon) gives her somewhere to belong. Then Ernessa Bloch (Lily Cole) arrives, a pale new student who pulls Lucy away, and the school's dead begin to add up. Mary Harron has Rebecca write it all down, sure that Ernessa is to blame and increasingly alone in thinking so.
