This episode contends that aliens came to Earth to mine gold. Examined are the legends of cities of gold such as El Dorado and Paititi, Lake Puray in Peru where UFO sightings may be linked to gold beneath the lake, the gold-creating device called the Philosopher's Stone, the Hall of Records beneath the Great Sphinx of Giza suggested to be a repository of ancient knowledge, a Medieval church in the French village of Rennes-le-Chateau that may hold the secrets of alchemy, and Scotland's Rosslyn Chapel where a helix-shaped pillar, suggested to represent DNA, may be the hiding place of the Holy Grail.

Could gold be the ultimate link between humans and aliens? Locals in Cusco, Peru believe UFO sightings are connected to lost gold at the bottom of Lake Puray. Some believe underneath the Great Sphinx of Giza lies an entire library left behind by extraterrestrials–a library stored on gold. A church in southern France is said to hold the key to alchemy–and a gateway to another part of the universe.
