Years after the fall of Camelot, a weary and disillusioned King Arthur, portrayed by Alexandre Astier, lives in exile, haunted by his past failures and the loss of the Round Table. His quiet retreat is shattered when a looming magical threat emerges, one that forces him to confront the ghosts of his former kingdom. To face this new darkness, Arthur must embark on a perilous quest to reunite the scattered and equally broken Knights of the Round Table, including the boisterous Lionnel Astier as Léodagan and the ever-loyal Alain Chabat as the Black Knight. This epic adventure, directed by Alexandre Astier, masterfully blends the signature absurdist humor of the beloved series with grand fantasy spectacle. As Arthur struggles to lead his dysfunctional band of heroes once more, the film explores whether a fractured legend can find redemption and reclaim its destiny against impossible odds.
