A group of friends goes to a remote cabin by a lake to rest and relax when unexplained things start to happen. Cameras flash in the night as something sinister stalks them and strange people appear and mysteriously vanish without a trace. As they start to doubt who they can trust among them, the creature behind these occurrences will reveal itself and is more terrifying than they can imagine.
Some vague bones are shown on the ground and someone strangle someone tight enough to draw blood (it sounds a lot worse than it is). Nothing too gratuitous.
Kinda yes, kinda no, it draws from indigenous American folklore and it's not super accurate and kinda cheesy but the indigenous people aren't presented negatively.
