“Cracks” follows an elite group of boarding school girls who compete for the attention of their free-thinking and glamorous young teacher Miss G (Green). She encourages them to indulge their desires, flout the establishment and – suggesting a world of adventures in her own past – pursue a life of independence and travel. The girls are thrilled to have such an inspiring teacher, but the status quo is threatened when the arrival of an exotic and beautiful Spanish student (Maria Valverde) disturbs the girl’s rigid and remorseless power structure. Favored girl Di Radfield (Juno Temple) feels especially threatened and, as Ms G’s hold over the girls progresses from emancipation to obsession, there are tragic consequences for everyone.
