When Martin hears that his mother is ill, he returns to Argentina, unaware that his life is about to change forever. Romina is a beautiful woman, who has lived in abject poverty since her father, Alfredo's assistant, has lost his job. Romina and her father try to survive to the best of their abilities, although they own a priceless emerald necklace, given to them by Alfredo on his death bed. When they finally decide to sell the necklace to better their situation, Romina's father is brutally murdered. When Romina first meets Martin, she is attracted to him, but wants nothing to do with him or his family, whom she blames for her dire straits. Martin is attracted to her, not knowing that they share a mutual pain. Unbeknownst to them both, their fathers were murdered by the same man - Victor, Martin's uncle. An unscrupulous man, Victor now heads the construction company, and will do everything in his power to destroy Martin, whose return hinders his malevolent plans. As Martin and Romina get closer, they realize that they share not only intense feelings for one another, but a desire to discover the truth and avenge the deaths of their fathers.
