A star is born in a time of both celebration and instability in this historical drama with music from director Christophe Barratier. In the spring of 1936, Paris is in a state of uncertainty; while the rise of the Third Reich in Germany worries many, a leftist union-oriented candidate, Léon Blum, has been voted into power, and organized labor is feeling its new power by standing up to management.

Wednesday is the day when children are not in school and stay at home. It is also the day when the parents are not there. In Nantes, in the spring, twenty or so carefree and boisterous kids between the ages of three and eleven take advantage of this day to make their parents go crazy. Emma, 9 years old and naturally romantic, decides that Roland, the little boy she met in the street, is unhappy and persuades her friends to adopt him. Victoria spends the day with Martin Socoa, an often distant father whom she learns to love. There are also Muriel, Bruno, Colette and Henri who take off and create panic in their parents' home, while Marylin lives the founding drama of her childhood with a mother of an unreal sweetness. Throughout these little stories, we realize that the world of children has its own logic, totally different from that of adults.
