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.

The story of Henry, a stand-up comedian with a fierce sense of humour and Ann, a singer of international renown. In the spotlight, they are the perfect couple, healthy, happy, and glamourous. The birth of their first child, Annette, a mysterious girl with an exceptional destiny, will change their lives.

Set against Paris' oldest bridge, the Pont Neuf, while it was closed for repairs, this film is a love story between two young vagrants: Alex, a would be circus performer addicted to alcohol and sedatives and Michele, a painter driven to a life on the streets because of a failed relationship and an affliction which is slowly turning her blind.
