Deep within the rainforest's heart, deep within its unknown part lies a Mayan city lost in the centuries of time. In its golden age, Nakanjo was ruled by a mighty warrior king named Jaguar Claw, who extended the city's domination over other Mayan cities. Later, a Spanish conquistador, Cesar de Leon, hears the fable of the riches of Nakanjo and is determined to make its wealth his own. Finally, Esmie Cummings, an archeologist, follows in her husband's footsteps to at last uncover the city, but as Esmie delves deeper and deeper into the mystery, she does not realize that she is endangering her own life.
