Behind Closed Doors was one of the last silent films released by Columbia Pictures. Set in a mythical Slavic country, the story concerns the efforts by a group of royalists to restore their deposed king to the throne. Opposing this scheme is secret agent Virginia Valli, whose motives seem very confused throughout the picture. Equally confused is American spy Gaston Glass, whose job it is to keep the king from returning to power and who, like the audience, cannot figure out what Valli is up to. Thirty years later, Columbia's TV subsidiary Screen Gems revived the title Behind Closed Doors for a weekly espionage anthology series. ~ Hal Erickson, Rovi
