Granny Jantzen lives with her three granddaughters Dick, Dalli and Angela on the small pony farm Immenhof in Northern Germany. Since the breeding of ponies isn′t profitable anymore, Granny Jantzen is struggling to keep the family property. During the summer break , young Ethelbert is spending his holiday with his cousins at Immenhof. While Angela has fallen in love with the wealthy land owner Jochen von Roth, Dick and Dalli have to put up with bigheaded urbanite Ethelbert.

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.

The pony hotel has just been opened, but so far no guests have arrived. Dick gets Ralf to design a brochure about the hotel. The girls and Ethelbert then lead the village children on horseback to Lübeck, where they all distribute the brochure - not knowing that Dalli has added some embellishments to the text.

In 1948, students from Berlin University take part in the filming of a movie about the 1848 revolution as extras. A dispute arises between Else and Heinz, who tends to dismiss the revolution as a comical affair. Two fiercely opposing camps form at the university. But Heinz begins to reflect, and reading about a young student who lost his life in the turbulent days a hundred years earlier slowly changes his attitude. The conclusion of the filming at the Wartburg also reunites him with Else.

A romantic drama directed by Hans Deppe.
