Prince Heinrich and Herbert Prince, a journalist, are very similar in build and facial resemblance, although neither is aware of the fact. Therein lies the secret of the memorable day the journalist enjoyed. Prince Heinrich, bored over billiards in the officer's quarters of his regiment, discards the game to take a brief nap, the journalist was involuntarily (at first) feted in his stead. Herbert has been granted leave of absence, and, before departing from his duties, persuades his friend. Bob Garrick, to accompany him. While Bob is busy packing, Herbert shaves off his moustache. It is then that the resemblance to Prince Heinrich is most marked, particularly as both Prince and journalist affect monocles. But neither Herbert nor Bob is aware of the resemblance and do not reckon when en route for the distant city of Waldeck that they are marked out for the distinction that awaits them.
