France, the beginning of the XIV century. Every night, Queen Margaret of Burgundy and her two sisters arrange orgies, to which beautiful nobles are invited. The young men were brought blindfolded, and after a night of love they were killed and their corpses thrown into the river, because the queen was afraid that her husband would learn about her adventures. One of her lovers managed to escape death. He knows the secrets of the queen, knows that she once gave birth to a son from him, claims that he has evidence that Margarita wanted to kill her father and blackmails her.
