Border Inspector Reitlechner fights in vain against a stubborn gang of smugglers led by the pretty innkeeper Retta. When a colleague is shot during an operation, suspicion falls on Reitlechner.

The mountain guide Jakob is a controversial figure. His supposed father dies and leaves behind a great heritage to the people. In the town they consider Jakob a bastard, because his parents were not married, which means that without a testament, the lands in which he lives do not belong to him. But the testament indicates that the inheritance corresponds him under a single condition, he must be the first person to climb the east face of Monte Verità. There is a French version of the film, titled 'Un de la montagne', shot the year after with the same script but with different actors and by a different director.

At his uncle’s behest, the young Karl-Heinrich, Hereditary Prince of Saxe-Karlsburg, is sent to Heidelberg to study for a year. After a joyless youth in the gloomy, stately Karlsburg Castle, the prince embarks on the most carefree period of his life. He falls hopelessly in love with Käthi, the charming daughter of his landlords. But duty calls: the prince is gravely ill, and Karl-Heinrich must return to assume his duties as heir apparent and future ruler.

As the title "The Queen's Heart" suggests, this early German black and white version of Mary Queen of Scott's eventful reign and death focuses on her emotional perception rather lyrically, with some songs, mainly by her.
