Moonshine season in Appalachia has begun. Tim and Tickle are back, as we are introduced to some old school shiners -­ all looking to grab a piece of a $100 million dollar jackpot – tax free. But with a new lawman in town, everyone will be watching their backs.

A breakthrough is made on Josh and Bill's underground still; Mark and Jeff build a copper still.

Jim Tom helps Mark and Jeff repair a broken still; Mark hunts a wild hog.

A storm threatens Josh and Bill's underground still; Tickle goes rogue.

Tickle recruits a new partner and tries to find a new site after splitting from Tim; Mark, Jeff and Jim Tom start work on a second still; deputy sheriff Chuck infiltrates a moonshine operation.

Tickle builds a new still. Josh gets angry when he damages the nearly completed underground still site. Mark and Jeff make a risky move when they sell some of their product in town. Jim Tom teaches Jeff's son Lance how to measure the alcohol by volume concentration of moonshine.

Josh and Bill find mold in their underground still; Jeff's wife and son set up a second still.

Tickle gets busted by an angry landowner, while Tim devises an ingenious new hiding spot for his back-up stash of shine. Then, Josh & Bill get into a bone-breaking fight at their new still site. Also, Mark bootlegs moonshine by canoe in the dead of night.

Gunfire erupts in the bamboo patch just as Josh & Bill fire up their still for the first time this season. Meanwhile, Jeff, Mark & Jim Tom run a batch of President George Washington's rye whiskey. Then, Tickle hits the skids when his still is sabotaged.

Tim searches for 200 gallons of moonshine in a lake; Tickle finds his former helper; Jeff protects his still from an intruder; Mike uses horse manure for something other than gardening.

Tickle asks Tim for help; Jeff, Mark and Jim Tom battle a swarm of yellow jackets; and Josh rescues Cutie Pie.

In this season finale, one moonshiner will go down. Tickle devises a bold but risky plan to sell Tim's shine. Then, Josh & Bill's still site is compromised while Jeff, Mark & Jim Tom brazenly run three stills. Finally, Deputy Sheriff Chuck makes his move.
