In 18th-century France, a series of brutal killings in the remote province of Gévaudan is blamed on a monstrous wolf, spreading terror through a deeply superstitious community. Sent by King Louis XV to restore order, war-hardened hunter Jean Chastel arrives to find a town ruled by fear, where a fanatical priest exploits the legend of the Beast to tighten his grip on power. As the deaths mount, Chastel’s investigation reveals that the true horror may not lie in the wilderness but in human cruelty, corruption, and manufactured faith. When political forces declare victory by killing an ordinary wolf, the murders continue, forcing Chastel into a final confrontation with both the real Beast and the men who created its myth. Bloodied and alone, he destroys the creature and exposes a lie that cost countless lives, leaving a broken town to reckon with the price of fear weaponised as faith.
