In the mountains above Piketberg, something monstrous is waiting.

When a government experiment is abandoned, the chemicals seep deep into a hidden cave, giving rise to a nightmare. Now, a colossal Adder snake has awakened, and when a group of college friends enter the cave for a summer adventure, it becomes a fight for survival none of them were prepared for.

In a desperate bid to escape the labyrinth of tunnels, Jamie and Judy Stander face impossible choices, watching their friends fall to the jaws of the beast while uncovering the terrifying truth about what lurks beneath their hometown.

If it gets out, Piketberg will never be the same again.
