Film Synopsis

A promising pianist, Marie leaves home to further her studies at the Lyon conservatoire.  She hasn't enough money to live on her own, so she moves in with her childhood friend Emma, who now lives alone in her apartment after the death of her father.  It isn't the easiest of co-habitations, as the piano student soon feels she is coming increasingly under the control of her old friend.  Gradually, Marie develops a profound fascination for Emma, who still hasn't come to terms with being abandoned by her mother.  Eventually, Marie finds herself torn between two conflicting impulses - the urge to run away from the strange young woman who has begun to exert a worrying, possibly malignant influence over her, and the desire to stay and devote herself to her piano playing.  It turns out that that both women have an intense need for each other and it isn't long before they become incapable of separating...
