Plot

In 1910 Manhattan, Victoria Van Brett is a bitter, domineering spinster who lives an isolated life with her half-sister, Caroline, in the palatial mansion built by their late industrialist father. Victoria keeps the home shuttered and rarely leaves, controlling the operations of the residence, as well as Caroline's daily life. The sisters' younger half-brother, Rip, returns home to wed Anne Darrow, a nurse who saved his life. Victoria believes Anne to be a social climber after the family money, and surreptitiously has Rip's name removed from the family will on his wedding day. She inflicts other cruelties on the wedding day, including sabotaging the organ during Anne's walk down the aisle.
