After enduring 19 years in prison for stealing a loaf of bread, Jean Valjean (Vincent Lindon) emerges a hardened man.
He seeks redemption by reinventing himself as a respected dignitary under a new identity. He promises Fantine (Noémie Merlant), a dying factory worker, to rescue and protect her daughter Cosette (Megan Northam), who is being exploited and mistreated by the deceitful Thénardier family (Camille Cottin and Benjamin Lavernhe).
As Valjean raises Cosette as his own, he is relentlessly pursued by Inspector Javert (Tahar Rahim). Amidst the social unrest shaking France, the fates of Valjean, Cosette, her lover Marius, and Javert become intertwined in a turbulent, revolutionary Paris.
Through struggles, sacrifices, and a deep yearning for justice, Valjean strives to complete his own journey of redemption and offer Cosette a future of love and freedom.
