Corazón salvaje (1968)

Francisco Alcazar is a wealthy landowner, who owns sugar cane fields. Francisco is married to Sofia, a severe and uncompassionate woman, with whom he has a son named Andres. Before his marriage to Sofia, Francisco had an affair with a married woman who was physically abused by her husband. The woman became pregnant and died when the child was 3 years old. This love-child is, in fact, Francisco's true firstborn.
