La mujer del puerto.

Perla, a prostitute and the star in a miserable cabaret in the docks, falls in love with a sailor without knowing that he is her brother. Tomasa, Perla's mother, tries to prevent this incestuous relationship at all costs, but fails to do so. Set in a sordid environment, the director makes no concessions in this tragic love affair, which is narrated from three different points of view.
