It marks a clear shift from his previous strongly historically connoted movies, but seduces by its well-referenced nature and a realism acquired thanks to its roots into Jérôme Kerviel's biography, L'engrenage : mémoire d'un trader.

Thanks to the Serge Denoncourt's staging and conjoint adaptation alongside Maryse Warda, Quebec obtained its own version of the musical on May 23, 2018, featuring ten young performers from Petit Chanteurs de Laval and the Mont-Royal choral groups.
