The Heir to Næsbygaard(1965)

Overview:

Landowner Martin Kaas lives with his grandson Martin at Næsbygård. Martin is an avid horseman. One day, his horse loses a shoe, so Martin goes to see the village blacksmith Mortensen, where he meets the blacksmith's foster daughter Elise. The blacksmith is known to be an honest and religious man, but no one but Elise knows how brutal and cruel he really is. Elise discovers that her foster father, together with the estate's manager Hermansen, is involved in many shady deals that are not in the best interests of the estate. Martin, who often feels lonely, forms a warm friendship with Elise. One day, Martin disappears, and a letter left on his bed reveals that he has been kidnapped and that only a large ransom can bring the boy back.
