Lauro(Victor Huggo Martin), her older brother, incarnates the ambition, greed and resentment, which he uses like arms on his way to the political and economic power.
Lorena (Aylin Mujica), her sister, is a talented and beautiful woman and at the same time suffering from culpability and addiction.
Don Julian is on the verge of dying and Maria Claudia (who studies in the USA), returns urgently to Mexico; but on her way she gets in an accident and doesn't arrive.
In the middle of her misfortunes, she meets Antonio (Sergio Basañez), an ex-soldier of the Gulf War, and they fall in love.
