The Greencorn family has lived in the foothills of the Smoky Mountains for generations, but with farming no longer an option, the best chance for survival has become the clandestine cultivation of marijuana. And this season, they're expecting their biggest crop ever, the one that will put them over the top. But with all their expertise and precautions, trouble ensues when they suddenly attract the unwanted attention of the local 'mountain mafia'. Southern archetypes meet current-day economic realities in GREEN CORN, a movie about the supply side of demand. Featuring music by reggae and dub legends by the likes of Lee Scratch Perry, King Tubby, and Burning Spear.
