Jean, a nimble nine-year-old orphan navigating Paris’ streets, survives by crafting and peddling small wooden headstocks while devising ingenious gadgets from scraps. His solitary life takes an unexpected turn upon encountering D’Artagnan, whom he boldly invites to share his modest boat anchored along the Seine’s edge. The pair forge a close alliance, with Jean’s swift agility, streetwise instincts, and knack for invention proving instrumental in guiding D’Artagnan through treacherous scenarios.

Though labeled an orphan, Jean harbors an unyielding quest to find his mother, Catherine, torn from him at age three—a silent drive fueling his resilience. His mischievous spark, quick hands, and perpetually barefoot silhouette embody his resourceful existence on Paris’ margins, balancing survivalist cunning with an undercurrent of longing for familial bonds.
