Plot

Bob Sharkey is given charge of a group of American espionage candidates. However, he is informed by his boss Charles Gibson that one of his students is a German Abwehr agent. He accepts the challenge of identifying him. He correctly chooses the student, who is using the alias of Bill O'Connell. Gibson reveals that O'Connell is actually Wilhelm Kuncel, one of Germany's top spies. His mission is to determine the date and location of the Allied invasion of Europe. They assign O'Connell a job in London that gives him full access to false information about "Plan B", the invasion of Germany through the lowlands, hoping that he will pass on the misleading information to his superiors.
