The evil lawyer wants to take over the estate, and the evil farmer Esben helps him. But if the good farmer Svend Åge gets the red cow Rosa to bellow while Niels Peder yodels, then the horse that the stable boy Morten is riding on the trotting track will run faster and win the race. Then the lawyer will no longer be able to take over the estate, but it could all go down the drain if he steals Rosa.
