Black Pearl (1994)

With 22 black pearls to cover her costs, a mysterious woman abandons a baby at an exclusive girls' school. Perla grows up there with her best friend Eva. one day, Tomas arrives and seduces Eva, leaving her pregnant. The two friends decide to raise the baby together and never let anyone know who the natural mother is. But on their way to meet Eva's family, Eva dies in an accident; Perla survives, and since she was found with Eva's purse, everyone believes her to be Eva. Perla decides to play along so she can keep the baby and make sure he receives everything to which he is entitled. But when they arrive at Eva's family's home, nobody wants "Eva" there--not her "grandmother," her "uncle," or her "cousin" Malvina--whose boyfriend is the slime who seduced Eva. But Perla takes control of the family's cosmetics firm, determined to secure the best future for her "son" Charlie, and she must deal with the family's intrigues to wrest the firm from her hands, the schemes by Tomas' family, who happen to be the firm's most tenacious business rivals, and the pressing attentions of Tomas, who cannot understand why Perla resists his charm, therefore chases her with every ounce of ardor he possesses. But Perla is not as immune as she seems and she doesn't know how close to love--and her real mother--she really is.
