Overview

In 1910 Manhattan, Victoria Van Brett, a bitter spinster heiress lives an isolated life with her sister Caroline. Her domineering urges go into overdrive when their half-brother Rip brings a new bride home to the family’s gloomy Fifth Avenue mansion, built by their late industrialist father. The title refers to a secret soundproofed chamber that the villainess uses to entrap her enemies.
