Wind Walkers(2015)

Sometimes dead is better.

A group of friends and family descend into the Everglades swamplands for their annual hunting trip only to discover that they are the ones being hunted. A malevolent entity is tracking them and they begin to realise one of their party may be possessed by something brought home from a tour of duty in the Middle East – a demon of war so horrible and deadly they are unaware of its devilish presence. Or are they facing something even more unspeakable, a legendary Native American curse about to unleash its dreadful legacy of thirsting for colonial revenge by claiming more souls?
