À vos marques... Party!

A quiet and introverted high school senior by the name of Gaby is asked by the school's principal to welcome and supervise the integration of a new student, Sandrine. Outgoing and cheerful Sandrine is the complete opposite of Gaby; yet, the two girls soon develop a bond and Gaby slowly comes out of her shell. Pent up emotions about a past accident and old friendships comes back to hunt Gaby after she learns that she will have to tutor Frédérick, the swim team's champion and school hunk.
