La espuela (1976)

Accustomed to always impose his will, Enrique is the prototype of a wealthy petty tyrant belonging to a family of noble lineage. The young María Isabel, coming from a family as powerful as Enrique's, is harassed by him until he manages to marry her. On the wedding night, Enrique forces María Isabel to all kinds of humiliations to satisfy his sexual appetites. After a while, the couple will have a son, but María Isabel feels totally disillusioned with her husband and everything that surrounds her.
