Mystery at Blind Frog Ranch

Duane Ollinger sinks everything he has into hunting for what he believes is a vast fortune of gold on his property; with each step he takes closer to finding the treasure, the land appears to hold on tighter and stop him in his tracks.

With an access tunnel to the underground cavern finally opened, and a tantalising clue discovered, Duane's son Chad takes a risky dive into the flooded cave system -- and what he finds defies all explanation.

Duane decides that the flooded cave is too dangerous to dive into again, forcing the team to explore new access points to the underground cavern system. But something lurking in the darkness forces everyone to reevaluate their safety.

While searching unexplored areas of the ranch for an alternate entrance to the cavern system, the team discovers mysterious ancient markings on a cliffside and a mining shaft dug deep into the mountain that could lead them right to the gold.

After a long winter, the crew returns to Blind Frog Ranch to strategize a new plan to get the box out of the underwater cave. And Charlie asks for help to investigate a mysterious death on the ranch.

The results from radiocarbon testing are in, which will tell Duane if the box is Aztec or not. Then, the men discover they are being surveilled by a high-tech camera mounted just above the cave entrance.
