De mujer a mujer (1987)

Miranda, an unhappily-married mother of two small children, falls hopelessly in love with Sergio. She abandons her family and leaves with her lover. Their time together is reckless but exciting. Miranda misses her children and longs to see them, but their father will not allow it, so she brainwashes her lover into killing her husband. He obliges, leaving behind some bonus dead bodies.
