Deep in the Amazon, a catastrophic sinkhole rips a wound in the earth, revealing a lost world that has been isolated for millions of years. For an elite team of scientists and survival experts, it’s the discovery of a lifetime. But their state-of-the-art expedition is unprepared for what awaits them in the crushing depths.

The ecosystem they discover is not just ancient—it's actively hostile. When they are cut off from the world above, the team becomes prisoners in a subterranean cavern of impossible scale, hunted by the environment’s apex predator. This is no fossil. It's a nightmare of evolution, a creature of immense size and power, with a terrifying, strategic intelligence.

Trapped between a raging underground river and sheer, unclimbable cliffs, the survivors must navigate the ruins of a lost civilization that worshipped the monster as a god. Their only hope is a hardened survival expert who must outwit a predator that has never known defeat. As the body count rises, they realize they haven't just discovered a new species; they've invaded a tomb, and the king is awake.

Perfect for fans of high-octane action, creature features, and unrelenting survival horror, this is a non-stop thrill ride into a lost world where humanity is no longer at the top of the food chain.
