Cracks

Cracks movie synopsis: Set in a strict elite boarding school in the 1930s, the story centers on a clique of girls who idolize their enigmatic swimming instructor, Miss G (Eva Green). When a beautiful Spanish girl named Fiamma (Maria Valverde) arrives at the school, Miss G's focus is shifted away from the other girls. Di has a crush on Miss G, and is the firm favourite and ringleader of her group. It becomes a triangle: Miss G gets increasingly obsessed with Fiamma, Fiamma is disturbed by Miss G and also openly disgusted by the teacher's hypocrisies and deceptions, and Di is terribly jealous and makes Fiamma's life hell. The bullying culminates in Di physically throwing Fiamma out of the school.
