The story begins 400 years ago, on the border between France and Spain, in the coastal region of the French Basque country, Labourd, populated by whale hunters and sailors' wives.

En 1609, un conflit local tourne aux accusations de sorcellerie. Henri IV nomme deux hommes pour juger sur place… Restitué dans une démarche historique rigoureuse, le procès du Labourd figure parmi les plus violents et les plus argumentés de la grande chasse aux sorcières qui sévit en Europe pendant plus de deux siècles.

Through a large-scale film intended for a wide audience, the unpublished analysis of this affair questions the mechanisms that led to these persecutions, which are still the subject of much debate among historians today.
