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.
