Henrik Ibsen's drama from 1882 in Ostermeier's vision since 2012. Dr. Stockmann discovers that the source of drinking and spa water is riddled with pathogenic micro-organisms, caused by industrial effluence. He wants to publish the findings in the newspaper and demands that the city council re-route the water pipes. Influential citizens and local journalists promise their support. However, his brother Peter, the mayor, raises some serious concerns: The economic prosperity of the spa town will be threatened. Suddenly the support for Stockman from the town's policymakers begins to wane. They spread seeds of doubt about his plans and try to cover up the fact of the contaminated water. But Stockmann insists on transparency and intends to go public on the matter. For him the affair has long since ceased to be about the polluted health spa, his target is society as a whole.
