ade during Bergman's tax-related exile in Germany, the film continues the story of Katarina and Peter EGermann, 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 film consists of a non-linear examination of his motivations, incorporating a police psychological investigation, scenes from the EGermanns' married life, and dream sequences.
