Synopsis

Marguerite is a young and brilliant mathematician, the only girl in her class at the ENS, entirely devoted to her passion. The day an error is discovered in her thesis, she is devastated. In a dizzy spell, she leaves the school, wiping out the past. She then dives into the real world, discovers autonomy, befriends the young Noa, and has sex for the first time. Matured by her experiences, it is in this new momentum that she manages to find a correct proof of her theorem.

Production

To show mathematics realistically on the screen, Anna Novion worked with French mathematician Ariane Mézard, who provided all the equations written by the characters in the film, so that they are all authentic. Moreover, Mézard even made real progress on Goldbach's conjecture, the goal of Marguerite's work, for the film.
