On the mighty Mississippi River, a tug boat captain, a raft riding pool shark, and a pair of frog catchers each set out to make their fortunes. And when they aren't struggling with the speeding currents and high waters of the river, they're dealing with the other obstacles that come at them fast and furious... A pool hustle goes south and turns dangerous, a crew runs into trouble when an old ship they're bringing home too tall to fit under a river bridge, and the fishermen building their business come across a territorial local standing in their way. But these men face the challenges head on, and brace themselves for a wild ride ahead.
The Mississippi River curves and bends from Minnesota to Louisiana… and so do the fortunes of the people out on the river. Gary and Eddie move up into the catfishing business, only to find that it's far more cut throat than they expected and they'll have to be creative to survive. While the Tubbs tug boat crew rush to save a sinking boat, Matt's rushes to save his own hide after a pool hustle gets out of hand. And an old treasure hunter with a new first mate at his side starts his journey. They all learn quickly that you never know what the river will throw your way.
Two fishermen are forced to make a dangerous decision.
