Before the First World War, Dr. Hans Stockmann had a practice in a small town. His powerhungry brother is the mayor of Bad Trimburg, which has developed into a respectable resort. Dr. Stockmann is called in to become the town’s chief physician. He considers the sanitary conditions to be intolerable and insists on a clean-up. His ambitious brother and all those who, till now, have profited well from the corner cutting, are, of course, against that for financial reasons. The doctor is condemned from all sides and the conflict escalates.
