Father Rodriguez, who has looked after Esteban since he was a baby, tells him a great secret on his deathbed: somewhere his father may still be alive. So Esteban decides to begin his search in the New World. With the help of Mendoza, a mysterious man who claims to have rescued him as a baby, Esteban hides as a stowaway, aboard the Esperanza. As they are about to set sail, he meets a young Inca girl: Zia.

The Olmecs place the Sun Power Unit at the bottom of their sunlight collecting crystal and activate it. However, the unit does not behave as expected and the Sun Power Unit begins to overheat. The High Priest of the Cities of Gold, who turns out to be Esteban's father, tries to shut it down using Tao's jar which is actually a control unit. But he could be too late.
