In April 1965, a U.S. Navy attack submarine, the Tulsa, sank off the coast of Brazil, during routine maneuvers. Six men survived, one of them Bart Millen, the captain. A reluctant hero for saving the other six, Millen is haunted with guilt over what happened. He moves to Bayville, South Carolina years later, to get away from the press. What Millen doesn’t know is that there was another survivor. His executive officer, Nathan Caden, managed to make it to shore and, nursed back to health by Amazonian sorcerers, now thirsts for revenge against his former commanding officer, whom he believes deliberately left him for dead. Caden follows Millen and his family and sets himself up deep in the pine woods and swamps of Bay County, biding his time until he can put into action a plan to discredit and destroy Millen. Adopting the guise of a renowned white witch doctor, long thought dead and gone, Caden terrorizes Bay County and the Millen family for months, until the reluctant son of a local black root doctor helps Millen turn the tables and defeat Caden’s plan.
