A funny story about the adventures of a French family during their summer vacation which goes not exactly as planned.

Florence and Bruno thought they had finally found balance in their relationship with their children when suddenly they had to face a new threat: parents! First, Bruno's mother, Monique, showed up. She had broken her leg and could no longer take care of herself. Her son naturally offered to take her in until she recovered. Then it's the turn of Florence's father, Henri, who has just been left by his partner. Now homeless, he is deeply depressed. His daughter has no choice but to offer him hospitality. Florence and Bruno's routine is disrupted, but they remain optimistic.
