A beautiful movie, even if I am not a Spaniard, and the historical perspective doesn't ring too much of a bell.
I would look at the movie as a relationship between a father and a daughter, and there for any father of a daughter (if both are sensitive and a bit introvert / taciturn), it would ring bells.
Father (only mentioned) and Son are on the opposite sides (of civil war, but that is not important), and the antagonism of their espoused cause permeates into their personal relation ship, and the son is thrown out/ moves out.
Wandering around for some time, he finally settles down at a remote place, opposite to his father's (north vs South, Freezing temperature Vs hot weather), with his wife and small daughter. He is the doctor in that small town, and people (and daughter), believe he has mystic powers (he might have).
There are mysteries in his life, some of which his wife knows (probably she knows most), but naturally not the young daughter (she was 8), which makes him more mysterious and interesting for her.
By accident she comes to know that there was another woman in his life (definitely before marriage), whom he had forsaken, but not forgotten. When she is again reminded (she is a starlet, and her one of the movies had been screened on the town), the longing and the memories awake. He is now in a dilemma, one side is his old flame (Irene), on the other, wife and daughter. He hovers on the edge, to abandon which side and jump on to which.
Had the movie been completed, probably I would have known some missing links - the actual story between Laura (screen pseudonym Irene Rios) and Agustin. But even without that it doesn't compromise the plot. It is just that he had been in love, got jealous (probably there was some one else too), and then got married and left the girl and the place. She could be instrumental in that as much as his father was, but that is my guess. In the movie, despite all misunderstandings, the flame burned in him, and another one was of the wife and daughter. Which one to extinguish ?
It has a strong angle on the father - daughter relationship and the lack of communication in case of both being introvert - and the ill effects of such relation, especially in crisis. It has a close relationship with many - including the author of Mary Poppins (and her relation with her father). In fact, one could almost say it is P L Travers's biography. At least as much we know of it (except only probably the other woman angle).
