Mona has completed her studies in child psychology and now wants to put her knowledge into practice: she becomes the tutor of two orphaned children in northern Argentina. To her astonishment, the boy and girl have become semi-feral, living with a housekeeper in a posh estate and being left to their own devices most of the time. Mona quickly realizes she must guide the two "lost souls" back to civilization, but the children resist with all their might. To make matters worse, José, the former gardener, keeps appearing, apparently seeking the boy's company. Mona believes he is responsible for the children's evolution. She doesn't believe the statements of the two children and the housekeeper that José has been dead for two years. Obsessed with her goal, she doesn't realize that the children have entirely different plans for her. Another take on Henry James' famous story "The Turn of the Screw."
