Mike Rowe works with Australia's northern coast Aboriginals, who have lived off the land for more than 40,000 years. It's a dirty adventure that leaves Mike speechless as he works and hunts (yes, hunts) with tribal leaders.

In Australia, Mike Rowe teams up with local business "Snakes Away" to capture a poisonous Eastern brown snake without getting bitten, then joins a posse of local "toadbusters" in their war against the cane toad, a non-indigenous species destroying the local ecosystem.

Mike and his crew travel deep into the Australian Outback to strike it rich with a group of opal miners. And then, with this already a dirty adventure with dangerous work and extreme temperatures, production is almost brought to a halt by a fly infestation.
