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.
