Dr. David Lane, tormented by his wife's tragic end, leads a scientific expedition into the heart of Papua New Guinea in search of a diabetes cure.

The team, delving into the unknown jungles, watches glowing orbs, deep into unchartered territory, blink in the distance. The natives call the animals, Pterodactyl-like creatures, death-eaters or Ropen, stalking at night with an appetite for humans and crocodiles.

Familial tensions rise when David's son, fiancée, and estranged brother join the expedition, adding a layer of unresolved conflict to the unfolding scientific mystery. As the team pushes deeper into ROPEN ISLAND, reconciling family dynamics becomes a high-stake endeavor.

The treacherous journey, rife with peril and ancient creatures, takes a dark turn when an injured team member, Billy, tests the limits of their commitment. Simultaneously, the looming threat of environmental devastation caused by a ruthless corporation casts ominous shadows, forcing the team to defend both the newfound creatures and the fragile ecosystem they live in.

As they grapple with the aftermath of their expedition, Dave's groundbreaking medical research on bat blood clotting unfolds, offering a glimmer of hope for diabetes treatment. In a chilling climax, the Lane Corporation emerges from the ashes, a grim testament to their relentless pursuit of the truth in Cryptozoological research.

The Lane brothers, driven by an insatiable curiosity of things unknown, embark on another global adventure, after the Skunk Ape sightings in Florida, promising more cryptid revelations lurking somewhere in the depths of the Everglades. .
