Corinne Jean-Jacques

A group of boys and girls go camping after winning a publicity contest. A bad boy infiltrates the group, and one of the girls falls in love with him. Another devotes herself to a comrade weakened by the war, and the novelist Clémence watches over this youth with authority, providing the theme for her next book.

As the red headed boy writes in his school book, a family is a group living under the same roof who can't stand each other.
