In his conquest of New Spain, Herman Cortes was assisted by the hereditary Aztec Princess, Malintzin Tenepal who became his chief interpreter and the mother of his son, Martin Cortes, who is often called the First Mestizo. Christened as Dona Marina by the Spaniards and known to the natives as La Malinche, this extraordinary woman was, and still is, a polarizing character in Mexico and Hispanic American culture. The ordinary life of college professor Margaret de Vega is forever changed when she discovers the six hundred year old memoirs of La Malinche containing the secret to finding the lost treasure of Montezuma. With the aid of retired Special Forces Colonel R.A. Lincoln, Doctor de Vega undertakes her treasure hunt along a rapidly deteriorating United States - Mexican border."
