Across America, there are isolated places that appear untouched. In these desolate and sprawling areas – known as killing fields – dozens of deaths remain mysteries, baffling anyone daring enough to investigate. Discovery Channel will return to the Louisiana swamplands as an active criminal investigation unfolds for the next instalment of Killing Fields. Shot in real time, the series picks up from last season as Rodie, Aubrey, and the team zero in on the infamous 1997 homicide of former Louisiana State University student Eugenie Boisfontaine. Rodie is more determined than ever to close the case, which has haunted him for nearly two decades.
