Thirteen-year-old Vic (Sophie Marceau) is new at her high school. She makes friends with Pénélope (Sheila O’Connor) and together they check out the boys at their school, looking for true love. Vic is frustrated by her parents, who will not allow her to attend the “boum”, a big party. Her great-grandmother, Poupette, helps her out, and Vic ends up falling in love with Matthieu (Alexandre Sterling).
