The Mysterious Cities of Gold

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.

Buffeted by a fierce wind and a wild sea, the Esperanza manages to sail through the Straits of Magellan, under Mendozas guidance. But now, the ship faces another trial of strength: it is in the grip of a hurricane.

After a dangerous journey, Esteban and his friends are washed up on a mysterious island. That night, a shadowy figure comes creeping towards them. Silently, the figure steals a chart and a pistol, then snatches up Zia. Esteban gives chase. He discovers a curious house in a tree, where Zia is a prisoner. To Estebans surprise, the mysterious shadow turns out to be a friendly boy of his own age, called Tao.
