Two doctors, a German and a Czech brain surgeon, meet in a Berlin hospital, unaware of how fatefully they are linked by events from a dark past. A trip to a congress in Prague and an encounter with the wife of his Czech colleague force the German chief surgeon to rethink his previous life. The film deals with the explosive topic of the extent and causes of complicity in the crimes of National Socialism.
