Warum Läuft Herr R Amok (Fassbinder)

With slicked-down hair and three-piece suits, dependable Herr Raab is a technical draftsman. He gets along with his colleagues although his boss wants him to go beyond technical cleanliness to problem solving. He's a dutiful husband; his wife's a social climber and pushes him to seek a promotion, but they also share sweet moments. He's a caring father, helping his son with homework. His parents visit; his mother criticizes his wife. Old School friends drop by, as do neighbors. Some comment on Raab's wife's expensive tastes. His promotion may be a long shot, especially after he gives a dull and tipsy toast at an office dinner. But why would Herr Raab run amok?
