We follow 24 hours in the life of a being moving from life to life like a cold and solitary assassin moving from hit to hit. In each of these interwoven lives, the being possesses an entirely distinct identity: sometimes a man, sometimes a woman, sometimes youthful, sometimes old. By turns murderer, beggar, company chairman, monstrous creature, worker, family man.
Ismael and Julie, in the hope of sparking their stalled relationship, enter a playful yet emotionally laced threesome with Alice. When tragedy strikes, these young Parisians are forced to deal with the fragility of life and love. For Ismael, this means negotiating through the advances of Julie's sister and a young college student – one of which may offer him redemption.
In the wake of her mother's tragic death, French teenager Junie transfers to a different high school.

Junie begins dating the gentle Otto Cleves, but finds herself intensely drawn to her youthful Italian language teacher, Nemours. When Nemours begins to reciprocate, serious complications ensue.
