Out in the jungles of Papua New Guinea, a research team is looking for rare bats in hopes they can find a cure for Diabetes, when they see something that shouldn't, couldn't be real, Pterodactyl's hunting in the night. The local's call them Ropen, or death-eaters, and now the team is after biologicals to confirm their identity for the scientific record. Can the team make it back to civilization? Or, will they become "lunch" in this mayhem, edge-of-your-seat action adventure?
