After the disastrous outcome of the Armada, Baltasar de Zúñiga manages to reach the Spanish coast accompanied by Juan Lobo, his bodyguard and comrade. Their mission: to update the king. After completing it, they will be able to rest. However, once on their way home, Zúñiga has a new mission for Juan: to accompany and protect two inquisitors who are being sent to investigate the disappearance of several girls from a village near Toledo. However, the situation in the village is much more complex than they thought and they will soon discover that a climate of terror has set in and the residents are claiming to have seen witches and demons in the streets. Now they will have to investigate whether Satan really has ascended from Hell to punish men once again or if what is happening in the town has nothing to do with demonic powers.
