Three Knocks After Midnight

Some doors are never meant to be opened.
Seven brothers travel to an isolated mountain village to film a documentary, unaware that the villagers have lived by one terrifying rule for generations:
**Never answer three knocks after midnight.**
At first, it seems like nothing more than an old superstition. But when strange voices begin calling from the forest and one of the brothers returns... different, the line between family and stranger begins to disappear.
Because sometimes the greatest horror isn't the creature outside the door.
It's realizing the person standing beside you may no longer be your brother.
