Yana Tsvetkova was crazy about the Czech prince Karl Stolberg, but she did not dare to say “yes” to him, valuing her freedom. However, she did not refuse her beloved’s request to go to Switzerland to settle some of his affairs - which ones, he promised to clarify later. Thanks to the generous prince, Yana was traveling alone in the compartment, but the conductor asked her to shelter a girl who had found herself in a company of suspicious individuals. Of course, Yana agreed. She didn’t know that the “poor thing” was in cahoots with some unpleasant guys and they were very interested in the wealthy passenger... So Yana found herself in yet another trouble, but every cloud has a silver lining - while getting out of it, she met... another prince!
