Capricho(1993)

Capricho is a Spanish drama series centered on a woman trapped in an unhappy marriage with two daughters. She's perpetually harsh with Cristina and baby Raquel, her anger seemingly without cause. The secret that haunts her: Raquel is not her husband's child, but the result of a long-standing affair with León, the man she's always truly loved. Her resentment toward Cristina masks the guilt and longing that define her life. As the truth threatens to surface, the family's carefully constructed facade begins to crumble, forcing each member to confront the consequences of hidden desires and broken promises.
