One to Another (2007)

Lucie is surrounded by four handsome young men sunbathing on the rocks, and a reticent voyeur several metres behind. We quickly learn, though, that she is not the object of everyone's desires and dreams here: rather, the object is Pierre, her brother and occasional lover. He intersects with all of their lives, often sexually, always emotionally and even musically, as front man for their small-town rock band. He is a magnet for every character, but he himself is unstable and narcissistic. We soon skip through time and learn that he disappears, leaving the others yearning for him. Then, it is discoverd that he is dead.
