All smiles to Audrey and Jerome. They have three wonderful children and they are passionate about their jobs. For a weekend, they entrust the two eldest to look after their little brother. Jérôme has to cover a rock festival and Audrey has to lead a seminar. At least, that's what they say...

The quartet then has no choice but to act to keep up appearances, but very quickly the varnish and nerves begin to crack...
