-Anouk, Marco, Fanny, Alex, Safa, Emma, Ahmed and many others go through high school with their heads full of projects, doubts and intense emotions. L'EFFET SECONDAIRE is also about friendships that change, unexpected rivalries, love affairs that are born, adults that take up too much space and trials that weaken.
