18th century France
A beast roams within the wilderness of Gévaudan.
No one knows what it looks like, where it dwells and why it kills.
Yet Rosalie Boulet might be the one who can shine a light upon the dark mystery.
After her younger sister is slaughtered by the Beast, she cannot but go after the murderous predator.
While she ventures into a world of death and despair it becomes more than apparent that the Beast of Gévaudan is not the only adversary she has to face.
Mankind turns out to be just as cruel.
