In steamy Shreveport, Louisiana, two musical legends-in-the-making come together: a whiskey-soaked country singer named Hank Williams and blues artist Muddy Waters. What they've got in common over several hectic days of drinking, singing and whoring is an interest in staying alive despite local mobsters, bent cops, and a truckload of Ku Klux Klansmen. Swimming with alligators is the least of this pair's adventures.
