The Plague of Florence(1919)

Suddenly appearing in Florence, a seductress causes Cesare, the city's ruler, and his son to both fall madly in love with her. The son, killing his father before an order to torture the woman can be carried out, then turns the city's churches into dens of sexual debauchery. Acts of wild abandon continue unabated until the arrival of Death, who brings with her a horrible plague to loose upon the city.
