Contraband

Danish freighter captain Andersen, unwillingly delayed for inspection by a British warship, wangles British shore passes for himself and his first officer...only to have them stolen by mysterious passengers "Mrs. Sorensen" and "Mr. Pidgeon." Unwilling to be taken advantage of, Andersen follows his strayed passengers ashore, and soon is caught up through one crowded night in the machinations of a German spy ring.
