France in the 14th century. A torn country, bleeding under the iron boot of English occupiers and the cruel arbitrariness of marauding mercenary companies.

In the smoking ruins of the desecrated city of Argentat, fate forges an unequal alliance:

Julien, the young scholar whose belief in law and order was burned in the fire.

Bastien, the gigantic farmer who had everything taken from him and whose heart now beats only for revenge.

Sir Hugues, the war-weary knight who believes he has long since lost his honor in the mud of battle.

United by a common, merciless enemy—the English mercenary leader they call only "The Vulture"—they raise a desperate symbol: a piece of charred cloth. But what begins as a personal vendetta soon becomes something greater. Their banner, known as "The Banner of the Crow", becomes the whisper of hope in the oppressed villages and the feared cry of resistance.

As a small guerrilla group, they take on a seemingly invincible enemy. But their courage comes at a high price. Every victory demands blood, and in the deadly web of betrayal, intrigue, and their own inner darkness, their rebellion threatens to shatter before it has even truly begun.

In a world of ash and steel – how much can a man sacrifice before he becomes a monster himself?
