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, it is she who most resembles him in drive and character. Florencia, the eldest, suffers from a heart condition that is driving her to an early grave, and the youngest, Renata, is a spoiled, irresponsible teenager.
Miranda's thoughts are on her upcoming wedding. Her fiancé, Fabricio Beltrán, is soon to return from Germany, where he studied for his Doctor´s degree. But Miranda does not suspect that Fabricio is not coming back to marry her, but her sister Florencia. Bertha de Aragón, her maternal aunt, deliberately brought the two young lovers together out of pure spite, to hurt Miranda, whom she has never been 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 Aragón.
Fabricio arrives with his friend Alejandro Luque, who believes Gonzalo murdered his father and is intent on seeking revenge. But his mind will be in turmoil when he meets Miranda. He will fall in love for the first time in his life, and this feeling clashes with his desire for vengeance. Miranda, too, is struck by an attraction she cannot understand, and in their love-hate relationship, they will hurt each other and learn the meaning of sweet sorrow.
Gonzalo’s business goes bankrupt due to the mismanagement of César, who is 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 will have to overcome the barriers between them, set by César, 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".
