Sabotage (A Woman Alone)

As German saboteurs infiltrate England with plans to blow up key industrial and civilian installations, the British spare no effort to trap the Nazis before they can complete their mission. Soon, Scotland Yard focuses their attention on a small theater, run by the charming Mrs. Verloc and her timid but peculiar husband. The Yard plants an undercover agent to investigate the theater further, and with that the conspiracy begins to unravel.
