À ma soeur!

Two sisters, Roxane Mesquida and Anais Reboux, are on holiday with their uninterested parents. Libero De Rienzo, an older student, starts courting Mesquida with the clear intention of deflowering her and when he succeeds, it is in the sisters' shared bedroom, which leads to both anger and bonding between the siblings. Reboux's frustrations begin to surface leading to a menacing and shocking ending.
