The opening images of bucolic nature are followed by a world of illness: “Even the trees have malaria”. And the young communists who take on this operation for sanitation find themselves in conflict with local superstitions. Many can’t imagine pitting themselves against Uzhmuri, the Queen of the Frogs who haunts the marshes. She is said to lead anybody who chances upon her territory down into the depths, where she forces them to marry her. Sadly, the film doesn’t show the Queen of the Frogs but instead a kulak; and after some breathtaking suspense, he is defeated.
