Mother Küsters Goes to Heaven (1975)

Directed by Rainer Werner Fassbinder

Frau Emma Küsters prepares dinner late one seemingly-ordinary afternoon in her seemingly-ordinary Frankfurt kitchen. She wants to add canned sausages to the stew; her irritating daughter-in-law thinks otherwise. But the point is moot: Ernst Küsters has not only murdered the personnel director at the soap factory where he's employed but succeeded that by committing suicide.
