Jordan Scott -- daughter of helmer Ridley Scott -- makes her directing debut with this thriller set at a British all-girls boarding school between World War I and II and starring Eva Green as a popular teacher and coach of the swim team. When a new girl arrives at the cliquish and hormonally charged institution, jealousies erupt, obsessions arise and, eventually, a student disappears in this film that also stars Juno Temple and María Valverde.
