The Louisiana Bayou has been home to many key moments in history, from early Native American settlements to the Civil War battles, and it's up to Shelby and the Professor to uncover the evidence and preserve the Swamp's history for generations to come.

And the Swampman calls upon his trusty Swamp Buggy in a desperate attempt to win over a new client.
