Plot synopsis: Behind the red gates lies Dyrehaven with the green beeches and the famous zoo hill - the motley world of clowns. Professor Labardi is behind the popular singer pavilion, where his young daughter, Gulnare, performs. After a rainy summer, there is an economic low tide on Bakken, and the family is tempted to seek help from Gulnare's enterprising suitor, Carlo Petersen. But Professor Labardi carries a secret: the clown family has family ties to the fine legal world outside the gates. There is conflict, money transactions, love, hypocrisy and villainous streaks when the fine world and the hill folk meet. Behind the Red Gates is a terrific folk comedy that takes us behind the attractions at the traditional amusement park in Klampenborg.
