ON THE ROAD... THERE ARE NO RULES. Life is violent and expendable at Hobo Junction, Tennessee. Only the strong or the street-smart survive. Here, Casey (Margaret Langrick) the con-artist meets a tough but disillusioned fighter named Bird (Paul Coufos). Seeing Bird as her ticket to a better life, the two of them strike an uneasy agreement and head to New Orleans to arrange a match with "The Man" (Jesse Ventura) - the mysterious king of bare-knuckled boxing. The road south is treacherous ... fraught with danger, fighting and disagreement. But the closer they get to "The Man," the closer they get to each other. Finally, near a backwater bayou named THUNDERGROUND, Bird battles his vicious opponent. It's a savage competition where there are no rules. One man wins... when the other dies.
