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

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; Todd goes rogue and opens a new cut behind the mine owner's back.

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 chases fix after fix to keep the plant running and chase their million-dollar goal.

Jack's birthday has arrived but there's no time for cake when there's a season goal to reach; Todd and the crew try to get to the bottom of what's causing Hot Mess to leak more than half the gold in the pay dirt.

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 paydirt moving before the deep freeze.

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.
