Under the guise of finding cryptid animals, Ace Corporation sends Alex Klasse, a Cryptozoologist and university professor, his associates, and a band of mercenaries to explore the Lost World of Patagonia. The crew boards a nuclear powered All-Terrain Tracked Carrier and takes a harrowing ride into the unknown. The expedition soon discovers prehistoric creatures still exist. But the dangers won't prevent a sub-team from leaving the group in search of rare jewels.

Lost World of Patagonia is a prehistoric thriller filled with murder, mayhem, and savage dinosaur action.
