Isabella de Montey, favorite of King Francis I, is accused of witchcraft and conspiracy against the crowned lover. The woman (and she is pregnant) is subject to an inquisitorial investigation and regulated torture. She gives birth to a child, unable to withstand the torture, cursing the king and his new mistress, the Countess of Chateaubriand. The birth is taken by the executioner Guillaume Chaperon. Inquisitor Henri Dengon orders the executioner to take care of the newborn boy.
Over time, the executioner's son Rene grows up, begins to show unusual abilities. He senses evil spirits. When Rene turns ten, he enters the service at the monastery of St. Dominic. This monastery is headed by Inquisitor Henri Dengon, who led the investigation into the case of the Marquise, Rene's mother.
A werewolf appears in the city of Cholet, which terrifies the entire district. Rene decides to find out: how to save a man who turns into a werewolf? He successfully does it with the help of a special device.
Rene is visited by a vision: he is meeting a stranger in black. The stranger claims that Rene's soul is between God and the Devil.
