From the Life of the Marionettes

7.3
Overview
Peter and Katarina are at a marital crossroads, but, when he brutally kills a burlesque dancer, their domestic squabbles are rendered trivial by comparison. In the wake of the crime, the film backtracks, painting a portrait of the fraught union between Peter and Katarina. When does a marriage go bad? What causes a member of the German bourgeoisie to murder an innocent woman?
