Albert West sits in the forests of central Mississippi, contemplating his life. He has been drafted into military service during World War II. During his deployment overseas, he meets Bo Landrum, son of a commercial fisherman from near Mobile, Alabama. Bo has an intriguing tale of sunken treasure back home.

After returning from war, Albert travels to coastal Alabama to join forces with Bo and his family, who try and find a submarine that supposedly existed during the Civil War. The submarine was said to have sunk while transporting an untold amount of gold. Danger arises when they cross paths with a secret organization following the trail to the same treasure.

Like a good pot of gumbo, where all the ingredients combine to form a winning flavor, murder, kidnapping, and secret societies, to name a few, fuse together to form an action-packed, treasure-hunting adventure. The appearance of a beast from south Louisianas folklore gives just the right Cajun spice to make the seasoning perfect.
