Troy Landry gets a call for help from anthropologist Dr. Duke Beasley who, as a part of an ongoing effort to shed light on forgotten communities, is on a mission to uncover lost cemeteries buried deep in the Louisiana swamps. Using a combination of modern technology and old-world methods, Troy helps assemble a team as they journey into the heart of the swamp to track down these vanishing gravesites before they’re swallowed by silt and time forever.
