Filles du feu - Season 1

1609, the three Elissalde sisters live freely in the Basque Country. Jeannette, the eldest, has always refused to take over from their mother as the healer in the region. Catherine manages a flourishing maritime trade which stirs up the jealousy of Lord D'Urtubie. Finally Morguy, naive and dreamy, struggles to find her place. Their world threatens to collapse when judge Pierre de Lancre arrives, commissioned by the king to hunt witches in the Basque Country.

After the wedding celebrated at the Château d'Urtubie, the judge of Lancre launches a witch hunt throughout the region to find Gratianne's accomplices. Jeannette, accused of witchcraft, narrowly escapes torture and discovers that she can count on her former love who has recently returned to the country, Damien. While Catherine and Jeannette are looking for a way to escape, they realize with horror that Morguy is under De Lancre's spell. 

De Lancre multiplies the lawsuits, resolved to get his hands on the perpetrator of the murder of the soldier found in the forest. To survive, Jeannette and Catherine surround themselves with new allies in the village and the castle, and begin to resist the authority of the judge. Under the influence of De Lancre, Morguy tastes the intoxication of power.

The judge of Lancre is ready to do anything to discover the place of the Akelarre, while Jeannette, finally accepting his gift, organizes the preparations in secret. Freed from the assaults of D'Urtubie, Catherine resolves to declare her feelings to Madeleine. But the worst is brewing when de Lancre entrusts Cariel with a new mission bringing him closer to the butcher than the doctor.   

After condemning the women captured at Akelarre to the stake, de Lancre sends the guard to settle in the houses of the village to watch over each inhabitant. Cariel begins his scientific experiments on the female prisoners. Despite the risk, Jeannette attempts to free the imprisoned women, and brews a deadly potion for the judge. At the castle, Catherine and D'Urtubie have a final duel.

Jeannette wakes up on Cariel's operating table. She uses tricks to save time and manages to get out of the laboratory thanks to the soldiers mutiny led by Zephyr. They are joined by the men of the village who have returned urgently to the Basque Country, with Catherine at their head. Battle breaks out at the castle. De Lancre, threatened, is reluctant to flee and makes one last victim...
