Shortly after he goes back to his parents’ house, Diego meets Julia Malaguer Podestá, with whom he falls in love.

Julia, however, is engaged to Mauricio Doval, a successful businessman who hides his bloody business affairs behind his zealous defence of organic and natural products.

Diego becomes a very close friend of Martina Mansur, a woman who lost her small son two years earlier and believes that Mauricio is somehow to blame for the death.

Diego finds out about her plans and, in order to prevent her from committing a crime, ends up saving Mauricio’s life.

Mauricio needs his scientific knowledge in order to carry out ambitious and dirty plans and had been after Malaguer even before meeting Julia.

Diego will find himself facing a dilemma: whether to compromise with the truth and take advantage of it, or else to fight as if from within hell itself in order to change it.
