They stop at an exclusive mountain hotel, where they are taken for a countess and her maid. Just before they are to be exposed, a burglary is used to cover their nonexistent property and funds, though the burglar turns out to be a conniving suave crook posing as a Baron that now demands Janet become his companion. Another guest, also of dubious background, becomes her protector, but a showdown comes as authorities close in on all of them.
