Armed with a treasure map and a magical divining rod, Danny and his two best friends, Pete and Frankie, form The Jolly Roger Club and search for buried treasure in the bayous of southeastern Louisiana. They encounter natural and supernatural forces in that strange, beautiful, and endangered world. In each instance, Danny must use his wits to rescue himself and his friends from danger. Danny's final test occurs on a remote island near the coast with a hurricane quickly approaching. Danny must come to terms with his ghosts, overcome his fears, and learn to believe in himself in order to save his friends.
