Todd is getting a jump start on his next season and heads to Colorado to get his best wash plant -- Holy Roller -- shipped to Alaska.

As Alaska's brutal winter threatens to end his season, Todd only needs 47 more ounces of gold to reach his million-dollar goal, so he works the night shift to keep paydirt moving. The final gold weigh might be a big win for Todd or another disaster.

With their million-dollar goal in sight, the Hoffmans' best working wash plant breaks down and can't be repaired; Todd's last shot is to get the Hot Mess up and running during an arctic freeze.

The Hoffmans discover a huge vein of gold that could save their season if they can get it out of the ground in time; as the mine equipment fails, pressure mounts on their mechanic, Randy, to keep it all running.

Hunter takes on the Arctic tundra when a geologist's lead points to crazy gold on the edge of the Hoffman claim; at camp, Andy works to turn paydirt from an ancient river channel into a big pay-off.

When Alaskan temperatures plunge, Todd and the team are caught by surprise. Their biggest wash plant is frozen and the Hoffman's rush to thaw out their other plants before they're iced out for the season.

To hit his million-dollar goal, Todd pushes his team to get a third wash plant delivering gold. As the mine ramps up, the road system needs to be overhauled so they can keep pay dirt moving before the deep freeze.

It's Jack Hoffman's birthday, but if the team want to reach their season goal, there's no time for cake. Todd and his crew must solve why the Big Trommel, aka Hot Mess, is leaking out more than half the gold in the pay dirt.

Desperate to run more paydirt, Todd fires up Big Trommel, but the plant is so worn-out, Todd's nicknamed it `Hot Mess'. The team try fix after fix to keep the plant running and chase their million-dollar goal.

Todd must deliver 300 ounces of gold in just seven weeks. To make it happen, his first step is getting Hot Mess, a massive broken-down wash plant, up and running. Later, Todd goes rogue and opens a new cut behind the mine owner's back.

The first family of gold are back with their biggest gamble yet. Todd Hoffman, his father Jack, and son Hunter tackle a gold-rich Alaskan mine with ragged equipment and a rookie crew. They have seven weeks to find gold before winter freezes them out.
