Summer of 36.

Summer 1936, Nice. The vacationing bourgeoisie, accustomed to the French Riviera and its refined privileges, is bewildered by the influx of new holidaymakers taking advantage of the first paid vacations. In this hustle and bustle, where two worlds coexist without attempting to understand one another, four women from different backgrounds become embroiled in a murder at the very chic Hotel Riviera. A crime that will completely turn their family life, romantic relationships, and professional lives upside down.
