The tragic destiny of two sisters
Years ago, tragedy struck the peaceful Nogueira family during a picnic near a river. Their two daughters, Ines and Marta, fell into the water and were swept away by the current. The father succeeded in saving the elder daughter, Ines, but lost his life trying to reach the younger one. The latter has been taken in by a modest family who adopted her and named her Diana.
Years later, when her memory returns, Diana decides to find her real family and to take revenge on her sister, whom she holds responsible for the death of their father and the miserable life she was forced to lead.
