Troy and his crew return to the Louisiana swamps to extract the valuable treasure trove of old-growth cypress logs they discovered last season. Determined to capitalize on a rare spell of high water, Troy, Pickle, and veteran swamper Timmy Aucoin follow a storied map to relocate the prized wood. Then using Timmy's specialized boat called the "log dog," and every ounce of swamp ingenuity they can muster, the team attempts to secure a payday for the ages.
