Belgian pop singer Lio might seem a little too hot to be teaching in a smalltown school. But this is France, which has a higher beautiful teacher to pupil ratio than any other European country. Mme. Solenska becomes the fixation of one 12-year-old pupil (Alba Gaia Bellugi), jealous of the attentions she appears to lavish on another. Who could blame her? Still, Myriam Aziza’s drama isn’t just about a teacher in trouble. It’s also about the sheer hell of being on the cusp of womanhood. Aziza co-wrote the script with Sophie Bredier, a professor at the La Femis state film school.
