The son is missing
Chronology
A distraught father, Leon, takes his son camping in Appalachia. The local cult summons the evil Hanging Demon. The cult must confront the monster to find him amid a mounting body count.
Leon: What the heck?
Leon doesn’t pull the pin on the grenade during the climactic fight with the Hanging Man (the safety lever is clearly still there). It doesn’t go off, it’s better if he hits it. Leon takes his son, Jesse, on a camping trip in West Virginia.
That part really works on a low-budget level
He wakes up the next morning to find his son missing. He’s surrounded by a racist local population and a demonic presence that kills its victims with its ropes. I’m fine with a low-budget Deliverance-style trip to the mountains.
The lead is a functional, normal-looking father
The film struggles when trying to do high intensity supernatural visuals. They don’t have the budget or camera skills to do it right. It looks cheap and not even in a fun campy way.
