Where years ago Dick and Dalli, the 'girls from Immenhof' whizzed over the paddocks with their ponies and caused happiness and excitement, a lot has changed in the meantime. After his escape from East Prussia, Alexander Arkens found a new home with his mother (Europe's most beautiful great-grandmother) and his twins Bobby and Billy at Immenhof, which has become an agricultural property again. The two of them cannot imagine living anywhere else than here at Immenhof, where they spend a carefree, happy childhood together with their friends Kuffel, Zack, Eva, Lotti, Ole, the groom, or Hamlet, the evil ganter . But the homecomer Brigitte Voss causes complications, excitement and misunderstandings when it turns out that she is the owner of Immenhof.
