Jordan is a country musician living in the shadow of his father, legendary bluegrass musician Walker Bayne. A lifetime of poor decisions has led him on an endless tour of San Antonio dive bars, where between sets he resumes accruing women and drinking himself to the brink of disaster. Returning home to the Ozarks for the wedding of his twin brother, Jordan uncovers a dark vein in the Bayne family history: going back to the end of the Civil War, every generation of Bayne men have been twins—and one twin has always murdered their father. As old tensions resurface, Jordan searches out the surreal origins of his family and a way to escape the murder that is his inheritance. Following the brothers' every move are a mysterious hill dweller and his grotesque partner, a duo that will stop at nothing to make sure the Baynes' cursed legacy lives on.
