This tale of intermingled love and hate is directed by Rainer Werner Fassbinder, and is the 13th of the 33 films he made in his short life. It explores the universal dynamics present in close human relationships, even lesbian ones. Petra Von Kant (Margit Carstensen) is a fashion designer. Some time ago, she divorced the husband she no longer loved. Until recently, she has been in a fairly satisfactory S & M relationship with her assistant. When she develops an obsession with her fashion model, however, things become far more complicated.
