The blood orchid is a rare flower that holds the secret to eternal life and a fortune to the pharmaceutical company that finds it. Led by a two-fisted soldier of fortune, a scientific expedition is sent deep into the jungles of Borneo to locate and bring back samples of the legendary plant. Battling their way upriver, the explorers brave poisonous insects, ferocious crocodiles and savage headhunters, unaware that they are being stalked by an even greater danger: a nest of giant anacondas, who'll stop at nothing to protect their breeding ground, the blood orchid's home.
