Querida Enemiga (2008)

Lorena and Sara were raised together in an orphanage, and even though they have different personalities, they loved each other as sisters. Lorena dreams of starting her own family and loves to cook, while Sara is more materialistic; she has always hated the poverty of the orphanage, and she has more ambitions than values. Lorena's greatest wish is to become a chef and so, one day she says goodbye to the nuns who raised her at the orphanage and leaves to study cuisine in Mexico City. That same day, Madre Asunción discovers that Sara had stolen some of the funds of the orphanage. However, after she confronts Sara, she suffers a heart attack and dies. To avoid getting caught any further, Sara runs with her lover and accomplice Chalo, who is also the delivery guy/driver of the orphanage. But before she leaves, she goes through the files Madre Asunción had in her office for each orphaned child and stole two files – hers and Lorena's. When she finally reads them, she learns that she was found in the garbage dump, while Lorena was abandoned in the orphanage without explanation by her grandmother, the millionaire Hortensia Vallejo Vda. de Armendáriz. Sara's first impulse is to find Lorena and help her confront her grandmother and demand her rights, but then she reconsiders her options and decides to usurp her place in the Armendáriz gastronomic empire. Believing she would never see Lorena again, Sara thought her plan was foolproof.
