Suave butler Paul Lukas greatly admires his wealthy employer, one of those vaguely royal European noblemen who wanders around the continent carrying on romantic affairs. Lukas even practices copying the prince's mannerisms and pickup lines.
Traveling with the prince's luggage, he meets attractive and well dressed Elissa Landi and allows her to think he is the prince himself as they strike up a relationship on the train. They quickly fall in love - and Lukas is reluctant to tell her the truth, afraid that she will not be interested when she learns he is only a butler. Landi, on the other hand, is similarly shifty about her own identity....
Nils Asther is lots of fun as the real prince, who readily plays along with Lukas's game when the opportunity comes up. Landi is fine as the leading lady, sometimes very funny as she alternates between displaying allure and alarm. Lukas is good, too, as the slightly goofy impostor whose scheme starts to get out of control.
The plot and all its little devices - candles, champagne, unscrewing a fuse so the lights go out at the right moment - are not only silly but really rather predictable for the most part. Still, this is a solid entry in the early genre of comedies about misbehaving European royalty.
