After failing to deliver the first order of his career, Tony Coffman doubles down on the biggest order of his career--an unthinkable 500 pounds in only one week, or else. He's going to need all the help he can get, but his plan goes to hell when Greg Shook gets trapped in one of Mike Ross's booby traps. And when Corby "The General" Patton poaches Ron and Obie to his team, Tony confronts him with a warning--stay out of his territory, or he'll bury him. Father-and-son team Joe and Mitch Simpson have something way more lethal than words in store for out-of-state diggers. And with his back against his wall, Tony sends his shop worker Wayne Dancy to buy ginseng off some shady sellers in the most dangerous county in America--"Bloody" Mingo County. He'll be lucky to get out with the 'seng, and his life.

Chinese buyers place the biggest order of Tony Coffman's career--750 pounds of ginseng. It will get him rich if he fills it, but with winter rapidly approaching and Corby "The General" Patton billboards popping up all over West Virginia, it's a tall order. And worse, the market is getting a little more crowded with Tennessee moonshiner Tiny Roberson looking to buy up ginseng for his new moonshine recipe. Meanwhile, outsider Greg Shook ventures back into local territory searching for 'seng, but ends up running for his life from local father-son duo, Mitch and Joe Simpson. Ron and Obie put aside their differences and join forces, hoping for one last big score of the season--but they'll have to infiltrate the dangerous, gun wielding pot farmers to get it.
