Plot
In 1609 in the Basque Country a group of five teenagers are captured and arrested as main suspects of witchcraft, as they celebrated a party in the woods. Judge Rostegui, given the task of purifying the region by the King, arrests the girls and accuses them of witchcraft. He decides to do whatever it takes to make them confess, and tell him what they know about the akelarre, a ceremony with magical connotations, during which the Devil is said to initiate his servants and mate with them.
Even though they deny it, and there is no evidence against them, they are arrested and tortured in order to force them to sign a written confession. After another of their friends is arrested, one of the girls, Ana, confesses to be a witch, claiming she cast a spell on the rest of her sisters and friends. Ana's plan is to gain enough time for the girls to organise an escape when the men of the village return from their fishing. As a result she spends a whole day confessing a detailed sabbath festivity - in reality a twisted version of the party she and the girls held before their arrest.
Judge Rostegui postpones the girls' execution when Ana says she can only use her magic in every full moon night as she feels Lucifer's calling. Her portrayal convinces Rostegui who offers to deliver every item for the sabbath which causes some of his men to distrust him. One of his allies warns him that after the full moon, the village men will return and the girls will be set free. Rostegui rushes the girls' execution and takes them to the woods for the ceremony with all of Ana's specifications. Understanding their situation, Ana leads her friends in a dance demonstration as they play along as witches and sing in the Basque language. Rostegui is entranced, but all of his men, along with village's priest are frightened of the "sabbath".
Ana and the rest of the girls flee as Rostegui and his men have an argument; a chase through the woods ensues until the girls are cornered at a cliff. As they join hands, one of the village women elders sings in Basque about the tide brought by the full moon which motivates the girls to jump off from the cliff to Rostegui and his men's surprise.
