Teresa is a young woman dominated by her own greed. She would rather lie and cheat her way out of poverty than find an honest job. Her parents have made great sacrifices to give her a good, decent life, but Teresa wants more, a lot more. Mariano, Teresa's boyfriend, is truly in love with her and stands behind all of her decisions; Teresa, however, sees him merely as a convenient accessory, someone always eager and ready to do her bidding. Time and again she will use her beauty and cunning to run after other men with power and money.
