Synopsis from AllMovie:
A teacher who prides herself on being different meets a student who matches her nonconformist nature in this period drama. It's 1934, and Miss G (Eva Green) is a teacher at a private school for girls near the eastern coastline of England. While most of the teachers at the school are severe and strait-laced women who reinforce its reputation as a repressive environment, Miss G is more youthful and glamorous than her colleagues, and enjoys dropping hints of a free-spirited past to her young charges. Miss G encourages her students to challenge conventional norms of the day, and organizes a diving team at the school, which she oversees with great interest. Miss G also sees a danger in the cliques that dominate the school, and she tries to undermine them, much to the annoyance of Di (Juno Temple), who holds a high place in the school's pecking order. But things change for both Miss G and her students when Fiamma (Maria Valverde) enrolls at the school. Fiamma is from Spain and has a strong independent streak; she doesn't look to her peers for approval and insists on doing things her own way, which makes her all the more exotic and appealing to the other students. Fiamma also earns the approval of Miss G, but before long rumors begin to spread that the teacher's interest in her new student is more than academic.
