Marguerite is a brilliant young mathematician with the quixotic goal of giving a solution to Goldbach's Conjecture about numbers. Her supervisor Werner seems to be on her side, until he hires a second student, Lucas to help him prepare for a very important conference in Lausanne. With no time to help Marguerite prove some equations, her algorithms are taken apart in a seminar, leading to her dramatic exit from the prestigious Ecole Normale Supérieure. The girl is forced to reevaluate her limitations without, however, giving up the pursuit of her dreams.
