BLACK WATER: ABYSS

An adventure-loving couple convinces their friends to explore, with a guide, a remote, uncharted cave system in the forests of northern Australia. With a tropical storm approaching, they run into the mouth of the cave, knowing they’ll be safe underground. But when the caves start to flood, tensions rise as oxygen levels fall and they find themselves lost, disoriented, and trapped.

But the dank air and rising water are the least of their worries. The storm has brought in a monstrous predator. As danger mounts, long-kept secrets emerge and the friends turn on each other in a frantic fight for survival.
