In 1933, Mississippi was in the throes of both the Great Depression and Prohibition. Dirt-poor living was the way of life for most. Some folks were forced to turn to any means possible to put food on the table. In Winchester County, the Lawtons turned to brewing moonshine to make ends meet. Though dangerous and illegal, their operation ran smoothly until John Kirkwood, a highly ambitious federal revenue agent, came to town.

Thanks to a dirty deal with a man with deep pockets, Kirkwood sees ridding Winchester County of its moonshiners as his way to fortune. Enlisting the aid of the corrupt local sheriff and a squad of bandits and goons, they launch a brutal rampage against local 'shiners, piling up bodies along the way.

Henry Lawton works for his father in the family moonshining business. Henry also happens to be one of the best bootleggers around and runs the dark country lanes delivering his daddy's corn whiskey. At 19, he's tough as nails and knows the backroads like the back of his hand.

Henry is also in love with a young woman. Iris is a beautiful, intelligent, artistic young woman who has captured Henry's heart. Unfortunately, Iris is the granddaughter of Pearl Broussard, the woman the locals call the "witch of Winchester", which is a whole heap of trouble in itself. To make matters even worse, Henry is White. Iris is Black. In 1930s Mississippi, such relationships are recipes for certain disaster.

When Kirkwood and his band of bandits strike close to home, seemingly wiping out the Lawtons in one horrendous night, it seems like all hope is lost. Pearl Broussard uses ancient magic known as the "arts dark" to summon a magical force known as the "spirit of the trees" with only one thing on its mind: vengeance.

The best weapon against the evil of man is the supernatural. When the spirit of the trees walks free, evil runs in fear.
