Year 1703: the tyrannical madness of King Louis XIV of France has taken hold. The Musketeers hatch a plan to eliminate him and free his twin brother Philip, who is imprisoned on the island of Saint-Marguerite, but before they can act, he is executed. The Musketeers subsequently manage to recover Philip's body and, together with some loyalists to the monarchy, capture Louis. Louis XIV, in chains, is now victim of a ritual of blood and power.
