Father Woudenberg uproots his family from the big city to rustic village Ravenhorst to start exploiting the vineyard that comes with the 'old inn' he bought as new home. Firstborn Tjomas feels his life is shattered, second son Maurits soon settles in, kid brother Joost enjoys playing in the woods and thus stumbles upon a magical gate. Trough it, the siblings will be transformed into mounted knights fulfilling the prophecy of saviors for the countship Ravenbosch's fortified capital Raveleijn. From there, the oppressive count-sorcerer's wife magically calls on the Woudenberg family.
