The drama described in the film was played out in 1933 in one of the French provinces. The mansion is home to a widow and her emotional daughter. They employ two sisters as maids, but the relationship between women is not easy. Social inequality is too great for the hostess to honor the servants with communication. In this tense atmosphere, feelings and emotions are heightened, and the tense relations between the sisters gradually develop into something vicious – they begin to experience sexual attraction to each other. This obsession becomes the cause of the tragedy that claimed the life of the hostess and her daughter. The film is based on real events that really took place in France.
