Don investigates reports of bizarre cult activity in the Louisiana bayou. He joins in an exorcism to ward off evil, seeks out ghostly orbs said to guard long-lost treasures and hunts for a demonic beast in the murky wetlands near New Orleans.

Don ventures into a remote jungle to come face-to-face with a deadly curse. An ancient civilization once ruled what is now eastern Honduras from a secret city. Don hopes to uncover clues about who they were and why such lethal dangers still protect it.
