Legend has it that there is a treasure of immense value buried in the Philippine jungle - now a team of American experts, with the help of the only surviving witness, try to uncover the clues to solve the greatest mystery of WW2.
In the season finale, the team finally reaches the void space under the waterfall, giving them a glimpse of what lies inside. But excitement is short lived when unexpected visitors get in the way. Meanwhile, the team investigates leads for other possible Yamashita treasure sites throughout the Philippines, uncovering evidence that any one of their 25 new treasure maps could lead them to the Lost Gold of WWII.
When a dead end in the tunnel threatens to close the door on exploration, a back door opens. Using their recently decoded Golden Lily map, the team discovers new access points, hoping to get under the waterfall by any means necessary.
As the team finally gets to the bottom of Breach 6, startling new evidence suggests they might be too late; the miners trigger a hazard in the tunnel, which threatens their safety; Bingo unearths alarming evidence a little too close to home.
Breach 6 reveals its first piece of treasure; Levi and Geo come up with a creative solution to get past a mysterious collapse in the tunnel; while drilling toward a possible treasure vault, John and Rob make a startling discovery.
John plans to drill across the mountain; Rick finds an artifact at Breach 6 that could confirm Japanese military presence; Levi and Geo make a grim discovery in the tunnel; Bingo meets someone with rare and valuable knowledge.
Another promising clue at Breach 6 leads Rick to believe they're on the right track. John hits a roadblock on his search for a tunnel entrance near the waterfall, Bingo makes an incredible discovery that could lead him to Golden Lily treasure maps.
With new evidence suggesting the location of a possible treasure vault beneath the waterfall, John is determined to find a way in, but Mother Nature is wreaking havoc on his plans; information is revealed about the knife that was found.
An advanced satellite scan of the mountain reveals metal deposits underground; the team targets three sites believed to be the access points to Yamashita's gold: a waterfall, a crater known as Breach 6, and a camouflaged tunnel.
