Synopsis:
Diana Prince and the Holliday Girls board a ship equipped with a new anti-submarine shield invented by Wonder Woman. The shield proves effective during the first attack, but a spy aboard ship disables the shield and steals the key component, a pressure coordinator.

The ship is sunk, but Wonder Woman rescues the Holliday Girls and the crew. She drags them to an island, but is soon captured by Nazis. Steve Trevor assists with the rescue. After the Nazis are defeated, Wonder Woman exposes Bertha Nagle, an engineer's secretary, as the spy.
