In an austere and remote all girls boarding school, the most elite clique of girls are the illustrious members of the schools' diving team. DI, LILY, POPPY, LAUREL, ROSIE and FUZZY are the envy of their fellow pupils who watch on as the girls compete for the attention of their glamorous teacher MISS G (Eva Green). MISS G in turn thrives on the attention she receives from her girls and believes it is her role to teach them the ways of the world.
