Mystery at Blind Frog Ranch, Someone Was Here

Duane Ollinger believes there's a fortune of gold buried beneath his property in Utah. He's not going to stop until he finds the treasure, no matter the cost.

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

Duane and the team search for new access points to the underground cavern system. But something lurking in the darkness forces everyone to re-evaluate their safety.

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.

Duane employs ground-penetrating radar to scan the land, leading to a mysterious finding. Trespassers prompt Charlie to increase security on the ranch.

As winter closes in and the digging season nears its end, Duane takes a final shot at getting into the underground cavern, and uncovers a whole new mystery about the land.
