Although deeply in love with her boyfriend - and indeed sleeping in the same bed with him - a schoolteacher cannot handle the almost complete lack of intimacy he will allow. Increasingly frustrated, she gradually finds her sexual appetites leading her into ever more risky situations, including a developing one with the headmaster.

A Ma Soeur! is a provocative and shocking drama about sibling rivalry, family discord and relationships. Elena is 15, beautiful and flirtatious. Her less confident sister, Anais, is 12, and constantly eats. On holiday, Elena meets a young Italian student who is determined to seduce her. Anais is forced to watch in silence, conspiring with the lovers, but harbouring jealousy and similar desires. Their actions, however, have unforeseen tragic consequences for the whole family.
