Miranda San Llorente is a modern, spirited young woman who seems to have it all: beauty, wealth, and a loving heart. Her millionaire father, Gonzalo San Llorente, has placed his hopes on her as his successor because, of his three daughters, she most resembles him in drive and character. Florencia, the eldest, has a heart condition; Renata, the youngest, is a spoiled, irresponsible teenager. Currently, Miranda's thoughts are on her upcoming wedding. Her fiancé, Fabricio Beltran, is soon to return from Germany, where he studied for his doctor's degree--but Miranda does not suspect that Fabricio would rather marry her sister Florencia. Bertha de Aragon, her maternal aunt, deliberately brought the two young lovers together out of pure spite to hurt Miranda, whom she was never able to manipulate because the girl is not deceived by her aunt's pretense of kindness. Miranda is a constant reminder of the woman Bertha hates the most: her own sister, Fernanda de Aragon. Fabricio arrives with his friend Alejandro Luque, who believes that Gonzalo murdered his father and is intent on seeking revenge. But his mind is in turmoil when he meets Miranda and falls in love for the first time, which clashes with his desire for revenge. Miranda is also struck by an attraction she doesn't understand, and in their love/hate relationship they hurt each other and learn the meaning of sweet sorrow. Gonzalo's business goes bankrupt because of the mismanagement by Cesar, Fabricio's brother and Bertha's accomplice. Gonzalo goes to jail and Miranda must find a way to rebuild not only the family fortune, but the family itself, including her mother Fernanda, who left years ago because of Bertha's gossip and underhandedness. Also, Miranda and Alejandro must overcome the barriers between them, set by Cesar, who loves her, and Bertha, who fell in love with Alejandro at first sight. In this struggle of feelings and passion, of power and pride, Miranda and Alejandro will discover that only those who cause them can heal the wounds of love.
