During the heyday of the French Revolution, the days of the week and the names of months and seasons were renamed in an attempt to deepen the effects of the rebellion through linguistic means. Messidor was the name given to the harvest season at that time. In this story, two contemporary Swiss girls are called the Messidor sisters by a policeman, indicating that they grew up in prosperity. Despite the comfortably banal outward appearance that the two have serene and secure lives, the girls experience many difficulties, including an attempted rape.~ Clarke Fountain, All Movie Guide
