Torrential rain threatens to drown out the season for the Dirt Dogs. Remote prospectors Henri and Kellie hit a hot streak, while the Gold Gypsies strike a once-in-a- lifetime find.

The ‘Dirt Dogs' fightback comes down to a make or break clean-up, Chris and Greg surf a wave of reef gold, and Henri and Kellie risk life and limb to stay on a hot streak.

Kellie and Henri face poachers and a crippling dry streak, and the 'Dirt Dogs' must break new ground to stay in business. Plus, the 'Gold Gypsies' seek out precious reef gold.
