Baptiste is a solitary type. A teacher in southern France, he never stays in the same job for more than three weeks. He helps one of his pupils, Mathias, and meets his mother, Sandra, a beautiful woman who’s led a bit of a wild life. Within a day, the trio have formed a bond not at all unlike the beginnings of a family for those who have none. Unfortunately, Sandra owes money and something serious could happen – and thus she must hit the road, fleeing once again. To help her, Baptiste must look back upon the origins of his own life – at the most painful and secret parts of himself.
