Seance

Camille Meadows (Suki Waterhouse) is the new girl at an elite boarding school for girls, and the older students bring her into their circle with a late-night ritual meant as a joke. They call on the spirit of a former student who is said to haunt the halls. Simon Barrett keeps the girls' friendships under strain from the first hour, and the question of who among them can be trusted grows sharper as the night wears on.
