Hello, Sister! 1933

Gable is Giovanni Severa, a pilot in the Italian Air Force. He meets Angela (Hayes), an aristocratic daughter of a prince (Stone). Her father opposes their romance but they steal moments together anyway. When Giovanni goes off to fight in the 1914-1918 war, Angela waits for him so they can get married. When she learns he has died in combat, she knows she will never love again and joins a convent.

The film is based on a true incident in Le Mans, France in 1933 called the Papin murder case, where two sisters brutally murdered their employer and her daughter. The murder shocked the country, and there was much speculation about the sisters, including allegations that they were having an incestous lesbian affair with each other. The Papin case was also the subject of The Maids, a play by Jean Genet written in 1949 that was adapted into a film in 1974 by Christopher Miles. It starred Glenda Jackson and Susannah York as the maids, and Vivien Merchant as their employer.
