Their worst nightmares lurk in the darkness…

The offspring of four cursed families risked everything to defeat the nightmare that haunts their bloodlines. But when an eerie melody chimes through the trees, they know the Bell Witch has returned. Her harvest of souls has begun, and they are running out of time.

Vowing to put an end to the evil presence, the four survivors venture into a network of caves. They descend deeper into the dark, flooded tunnels only to find demonic spirits tormenting them with nightmarish visions of the past—bitter secrets their families have fought hard to keep buried.

As the frigid water begins to rise, the survivors are confronted with the most horrific terror of all. They soon realize that the only way to get out of there alive is for one of them to make the ultimate sacrifice.

Will they survive? Or will they drown in the shadowy depths of the Witch's cave?
