This is the story of Beba Marturano, a charming young woman who has recently earned a degree in architecture. Beba has always lived a comfortable life; her only true hardship has been the loss of her father, Tomás Marturano.
She first lost him when he divorced her mother, and then again when he died in a suspicious accident far away from her. Beba grew up tormented by the hatred her mother, Emérita, instilled in her toward Mara Marturano and Brando León.
Beba suffers from amnesia, and during this period, she falls in love with Brando. Upon regaining her memory, she realises that she is deeply, hopelessly in love with him.
Their love seems impossible, however, because Beba is already married to Urbano Durán, a humble labourer consumed by jealousy. Urbano suffers from a severe inferiority complex, wrongly believing that his modest background and lack of formal education make him lesser in Beba's eyes. Consequently, he constantly doubts his wife's love and sincerity.
Eventually, Beba learns that Brando, who had been deceived by Mara, was not responsible for her father's death. She also discovers that Urbano, who manages to graduate with an engineering degree, has likewise been manipulated by Mara.
In the end, Beba is forced to choose between the two men who have shaped her life: Brando León or Urbano Durán...
