Holy Motors

We follow 24 hours in the life of a being (DL) 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 to the point of dying; sometimes destitute, sometimes wealthy. By turns murderer, beggar, company chairman, monstrous creature, worker, family man… It's clear that DL is playing roles, and plunging headfirst into each - but where are the cameras, the crew, the director? He seems horribly alone, exhausted from being chained to all these lives that are not his, from having to kill enemies that are not his enemies, having to embrace wives and children who are not his. But sometimes, conversely, we feel DL is wounded by having to leave, the moment his scene is over, other beings he would have liked to leave no longer.
Where is his home, his family, his rest?
