Accepted by the prestigious Conservatoire in Lyon, pretty young piano student Marie moves to the city and lodges with her childhood friend Emma, whom she hasn't seen for years. Emma is beautiful now, and a shell of mystery and secrets. Marie is a whirlwind of freedom, exhilarated by her independence and eager for new passions. Slowly the two young women are drawn together in a dance of desire which is not always reciprocal and not always safe, as their emotions wildly rise and fall. A desperate sexual and psychological obsession beckons.
