"I'd like to see how we look in 10 years..." Bruno, Momo, Alain and Léon meet up in hospital a few years after leaving school. They're waiting for Sophie to give birth. She was the girlfriend of Tomasi, their best friend who died of an overdose a week earlier. Together, they compare their fragmentary and contradictory memories of their final year at the Lycée Montesquieu... The first girls, the first political meetings, demonstrations, fits of laughter, rebellion against the teachers, harmless conflicts with their parents... and the anxiety of the "bac'"exam... "Remember how we looked 10 years ago..."
