Neutral Danish steamship Helvig, returning from America, runs foul of British contraband regulations and is led to a control port where Captain Andersen grudgingly allows by British officers with the promise that the ship will be allowed to proceed in the morning. Discovering that his landing passes have been stolen and two passengers are missing Mrs Sorensen and Mr Pidgeon, both agents for British Naval Intelligence Andersen rows ashore, following the two escapees on to a train bound for London. Pidgeon escapes in the London black-out but Andersen catches up with Mrs Sorensen. Both are captured by German intelligence, who substitute false plans for those carried by Mrs Sorensen. Andersen escapes and recruits help from a Danish restaurant nearby They rescue Mrs Sorensen who then slips away to inform the of the true message which she is carrying. Passengers and crew return to the Helvig in time to sail as arranged the next morning, when Andersen learns that Naval intelligence had been monitoring the events of the previous evening and he is congratulated oil his night's work.
