Sandra, the ex-novia, returns to haunt her former lover's new relationship. A 'puta' by nature, she toys with her successor, flaunting her curves and reminding her of the passion she once shared with Sandra's husband. The new wife, however, is no pushover. She fights back, turning the tables on Sandra, and soon both women are caught in a web of desire, their husbands unwittingly driving them towards a heated, forbidden encounter.
