Deep in the Amazon, aging archaeologist Dr. Carl Maia uncovers the skeletal remains of an unknown species, prompting an expedition into the uncharted depths of the jungle. Joined by his former student, Dr. David Reed—an ex-Navy SEAL turned marine biologist—David’s girlfriend, Dr. Kay Lawrence, an ichthyologist, and the expedition’s financier, Dr. Mark Williams, the team ventures into dangerous waters aboard the Maria, captained by Lucas. As tensions rise between David, who seeks to study the creature, and Mark, who wants to kill it, their rivalry pushes them toward catastrophe. When they finally come face-to-face with the enigmatic, prehistoric creature, their obsession and arrogance turn the expedition into a desperate fight for survival.
