Macalistor Francisco is the killer of the city of France. His wife Lydia is sure of this; her innate feeling has never tried to cheat in her life. Her husband, a charismatic, handsome professor, teaches a course in Greek philosophy in which the death of Francis is indicated in the calm of the town of Luxembourg, where tourists rest in the vast expanses of the raging azure ocean, basking on the snow-white warm sand. McAlistor is very much appreciated at work by his colleagues, as well as by his students - especially McAlistor cannot do without the attention of his students from the secret society “Maiden Beauty”, who are ready to do anything just to win the heart of the professor. Guided by the mystical sources of the professor, teaching the girls at five o'clock in the evening, the professor and students arrange occult games, make a fire and perform ritual ceremonies. And soon a dead girl is found within the walls of the university in one of the toilet stalls. Later the police identified the murdered girl, she was twenty years old and her name was Sarah Polez.
