King Philip IV of France, known as the Iron King, struggles to maintain the stability of his realm while his own household descends into scandal and betrayal. The narrative follows the cold, calculating monarch as he attempts to exert control over his weak-willed sons and their unfaithful wives, all while navigating the complex political landscape of 14th-century Europe. His daughter, Isabella, trapped in a loveless marriage to the English King Edward II, serves as a catalyst for the shifting alliances that threaten the Capetian dynasty. The story unfolds through a third-person perspective that emphasizes the rigid social hierarchies and the brutal consequences of dynastic failure.
