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.

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.

When a windstorm ruins visibility in the water, Chad considers a risky blind dive to extract the box. But when intruders are discovered, Duane and his crew realise that time is running out.

Chad makes a huge mistake, derailing the operation to drag the box out of the cavern. But when they pull out some of the box's contents, they are shocked by what they discover.

Determined to get into the cavern, Duane and his team explore new methods to find a dry entrance. While Chad takes to the skies in search of a natural opening. Eric thinks the radioactive rocks found in the box might show them where to dig.
