The story takes place in the pristine jungle of Borneo, where Bill (Johnny Messner) leads his expedition team through it, looking for a rare plant called "blood orchid". According to records, blood orchid has a mysterious power that can make people immortal, and the rumor that "almost no one has ever obtained it" has gradually made blood orchid a legend. This time, entrusted by a famous pharmaceutical company, Bill and his team decided to unveil the mystery of blood orchid. As they get closer and closer to the target, danger also comes unexpectedly. The power of blood orchid did not make humans rejuvenate, but made a group of snakes ferocious and terrifying. In order to move their huge bodies, they had to eat several times more food than before, and the humans who came presumptuously at this time became their best prey. On one side is the harsh ecological environment in the jungle, and on the other side are the vicious man-eating beasts. His companions died tragically one after another. Can Bill finally protect himself and save more lives?
