Laura Reagan, host of Creature X, wants to leave North America behind and step out from the shadow of her father's cryptozoological research. She leads her team to Umboi Island, off the coast of Papua New Guinea, to shoot a cryptozoological documentary about the mysterious Ropen, a bioluminescent pterosaur-like creature that has somehow survived extinction.<br/><br/>In a stroke of luck, Laura and her team see a mysterious purple light above the trees. Could it actually be what they're searching for? But the hunt for the Ropen takes a drastic turn when a body turns up in the Creature X camp. With satellite phones down, Laura and her team are stuck on the island with a murderer - and no chance of help.
