Paris in the late 1950s and early 1960s, the era of rock \'n\' roll and the Algerian War. Twelve heroes at the age when you have it all: high school, family conflict, parental divorce, after all, life in general - is quite difficult. So Michelle Marini is not so much concerned with learning as kicking, music, photography and reading. Thanks to his talent for scoring goals with a small red ball, he became a regular at the Balto bistro. There, in a hidden room nicknamed the Club of Incorrigible Optimists, he found shelter and friends-intellectuals who, to save their lives, crossed the Iron Curtain. This meeting changed Michelle\'s life once and for all. Because all these people were incorrigible optimists.
