Plunging the viewer—and the main character—into a true lion’s den, OLIVIA depicts a 19th century boarding school for young girls, one divided into two camps where all the shots, even the most underhanded, seem allowed. That’s because the two mistresses of the house, Miss Julie (Edwige Feuillere) and Miss Cara (Simone Simon), are engaged in a true turf war, and a war of the heart; competing for the affections of their students, they rouse passion, hatred and unexpected reversals of loyalties.
