THE MYSTERIOUS CITIES OF GOLD

The two children, Esteban and Zia, find out that they both wear the same strange medallion. The Esperanza crosses the Atlantic and nears the entrance of the Straits of Magellan, where wild seas and strong winds create terrible storms. Mendoza, the navigator, prepares to spend four days and nights at the wheel.

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

Esteban and his friends barely cross through the terrible Straits of Magellan before their ship, the Esperanza, sinks in a storm. Tossed around on a small raft and attacked by sharks, they're left in the middle of the ocean, with no provisions. But a seagull overhead guides them towards the closest shores, and they finally reach a small island.

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 Esteban's surprise, the mysterious shadow turns out to be a friendly boy of his own age, called Tao.

On a small island among the Galapagos, Esteban and Zia find a young boy living all alone: Tao. His ancestors left a magnificent ship, the Solaris, which contains their ancient secret knowledge, hidden in a temple on the island. Esteban and Zia want to use the ship to reach the mainland.

Gomez' Spanish galleon overtakes and attacks the Solaris, the sun-powered ship on which the children are travelling. They manage to outrun the Spanish ship when Tao discovers a wonderful secret solar power boost, just in time. At last, they reach the new continent.

After many adventures, Esteban and his friends finally set foot on the new continent. But there, they meet the soldiers of Governor Pizarro, men who think only of gold. They capture Zia and try to make her tell them the way to the Cities of Gold, but Tao and Esteban help her to escape.

Esteban and his companions escape from Pizarro, but their fabulous ship, the Solaris, is taken by Gaspard and Gomez. They offer to exchange the ship for Zia, and her secret. Trying to save Zia, and the friendly Inca people in the village, Tao blows up Gomez's ship, but sadly the Solaris is also destroyed.

Esteban and his friends are on their way to Zia's village, when they are surrounded by Spanish soldiers. The children manage to escape, and take refuge in an underground temple, where they meet the old priest, Pasha. To help them escape, the priest melts the pillar of ice that supports the temple roof, and it crashes down on top of him. The others just manage to get away.

Gomez captures the children and forces Zia to reveal the secret of the Golden Quipu. It is an Inca message which reveals that the Cities of Gold lie beyond the High Mountain Peak. In the night, Esteban and the children escape. They find a secret underground passage and set off for the High Peak.

The Spanish army follow Esteban and his friends to the Fort of the Black Eagle. Under cover of darkness, the Spaniards attack the fort, but Tao devises a rocket flare that repels the attackers, saving the fort. The three children leave the fort and at last reach the City of the High Peak, whose chief, Kraka, tells them that the medallions Esteban and Zia wear can open the doors of Sela, one of the Cities of Gold.
