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.
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.
In this war drama, three Nazi survivors are rescued after their battleship sank. Initially they are given heroes' accolades for their courage, but then it becomes apparent that these men actually jumped ship three hours before the boat sank. The men are tried and subsequently executed.
The Immenhof has been closed by officials, awaiting auction. In the meantime, Angela has died, so Jochen is now a widower. Oma Jantzen and Angela's younger sisters Dick and Dalli live with him in the forester's house. In order to save the manor house, Dalli has started a "pony circus" with the village children in the barn, while Dick has given up hope of Ethelbert ever returning.
Saleswoman Jenny is crazy about the painter Jack. But Jack does not want to marry, even though he loves Jenny passionately. So Jenny looks elsewhere to find the right man. She marries twice, but always ends up back with Jack and gives herself to him with no attachments. Will Jack and Jenny find true love? Of course!
