Vier Rakkers en Een Oude Jeep

Also known as Het geheim van de oude molen, Tarza, de wonderhond

A poor shoemaker and his wife inherit a farm in the southern province of Limburg. However, the farm has been heavily mortgaged by local real estate agent Bol who is planning to get his hands on the land -- which will soon be mined and therefore worth a fortune. With the help of their trusty German Shepherd Tarzan, the shoemaker's four young nephews decide to do something about it.
