Stubborn Fate(1992)

Original title: Ostinato destino

Carolina Rambaldi isn't fulfilled by her three children: Marcello, a lazy do-nothing, Lucrezia, a bossy type who produces a TV show, and Cesare, homosexual and malicious, who's a sociologist. When she writes her will, Carolina leaves her property to the one child who's married and had a child in the past year and a half.
