Colonel Garcia Valmira is a Spanish gentleman whose extreme wealth enables him to indulge his bizarre sexual tastes – without limit or restraint. To this end he has established a secret ranch or ‘estancia’ in a remote part of the desolate ‘Gran Chaco’ district of the Argentine. Its name is “Los Limitas” and here he keeps some forty or fifty desirable young women in a state of captivity and the most complete servitude.

A new guest has arrived at “Los Limitas”. Her name is Janina Casal a black-haired, vivacious natured, young women of the same age as Teresa. She is a favoured friend of the Colonel and, in her teens, grew up with Teresa. With the same kind of upper class background they were good friends until they fell out over a young man by the name of Carlos Estanza. Originally the friend and lover of Janina he switched his affections to Teresa and became her first and only lover. Furious at being jilted thus Janina never forgave Teresa and continued to nurse a burning hatred for the girl.
