Treasure Quest: Snake Island

The treasure hunters attempt to cross the treacherous Andes Mountains, chasing a two billion-dollar fortune. However, a landslide and the infamous "death road" immediately put them in life-threatening danger.

Smashing into a secret underground tunnel system, the team scours the subterranean cavern for a two billion-dollar treasure.

The team is trapped in an ancient, underground tunnel, putting their search at risk. Using just the gear they have on-site, they rig a remote-controlled camera that finds the expedition's most significant treasure.

Falling boulders threaten the crew and the dig site, and their dangerous solution could trigger a massive landslide. Meanwhile, deep underground, Shawn and Jeremy recover their first piece of Jesuit gold.

Chasing the treasure on two fronts, the team finds both evidence of a route used to transport the fortune and a Jesuit artifact that could provide critical information on the location of the treasure's final resting place.

The team improvises to deal with toxic fumes and must use explosives to blast their way to the treasure. Then the discovery of a key landmark puts the crew at the threshold of a fortune worth $2 billion.

The team risks their lives searching a massive tunnel with the valley on the verge of flooding. The risk pays off big, placing them on the threshold of solving the 300-year-old Sacambaya mystery.
