From the Life of the Marionettes (1980)

Made during Writer, Producer, and Director Ingmar Bergman's tax-related exile in Germany, the movie continues the story of Katarina (Christine Buchegger) and Peter Egermann (Robert Atzorn), the feuding, childless, professional couple who appear in one episode of "Scenes From A Marriage". After Peter perpetrates a horrendous crime in its first scene, the rest of the movie consists of a non-linear examination of his motivations, incorporating a police psychological investigation, scenes from the Egermanns' married life, and dream sequences.
