As the others try to help her, Jack attempts to retrieve the backpack. The log breaks, and she falls, hanging by her leg halfway down the pit. Jack orders her to throw him the backpack, but Sam threatens to drop the flowers into the pit unless he drops the gun. He has Sam cross the pit via a thin log to fill a backpack with orchids. Jack shoots Bill in the arm and forces the party to accompany him to the orchids. The group finds the raft just as Jack finds the blood orchids, hanging precariously above a pit in which a ball of male anacondas are mating with the queen. Bill throws his knife and impales the snake through the head, killing it and freeing Cole. The team follows and find him being constricted, but still alive. Sam uses a machete to behead it, but another snake captures Cole. The terrified Cole escapes from the caves behind the group, seconds ahead of the snake, which follows him through the hole and gets stuck. Bill tries to find Cole and Tran, but also notices Tran's lost flashlight floating with his blood surrounding it. He runs into Bill's partner, Tran, and as they return to the others, Tran gets pulled under and Cole tries to find him, however, Tran is eaten. Cole gets lost and panics after finding a skeleton. On the way they fall into a cave trying to escape from an anaconda. With no more material to make another raft, they hack through the jungle to beat Jack to the orchids and retrieve their raft. Jack uses the commotion to steal the raft. The others arrive just as it finishes, so Bill sets the building on fire in hopes of killing the anaconda, but notices that it already made its escape. An anaconda drops down from the rafters and swallows Gordon alive soon after she leaves the building. As Jack joins the others at the raft, Sam discovers Gordon and the spider bite. Jack is unable to convince him to allow the expedition to continue, so he paralyzes Gordon using a venomous spider. Gordon discovers Livingston's radio and gun and realizes they could have called for help long ago. Wanting to leave, they start building an escape raft. Jack says that since they must be close to the orchids, they should press on, though the others contend that there is no evidence that the orchids will have the same effect on humans. The team realizes that the snakes are unusually large in size because their lives have been extended through the orchids, which are a part of the local food chain. They find themselves in a small native village consisting of thatched huts and a disembowelled anaconda with a pair of human legs hanging out of the snake's abdomen.

They travel to Bill's friend, John Livingston, who lives on the river, to see if Bill can borrow his boat, but they find Livingston dead and his boat wrecked. However, most of the team demand that the expedition be called off. Bill assures them that it was the largest snake he has ever seen and that it should take weeks for it to grow hungry again. A giant anaconda emerges from the water and swallows Ben whole, but the rest of the team escape from the river. The team goes over a waterfall and has to wade through the river. Though their guide Captain Bill Johnson and his partner Tran Wu have misgivings, Jack convinces them to take an unsafe path. Ben Douglas, leave for a jungle in Borneo to search for a flower called Perrinnia Immortalis, otherwise known as " the Blood Orchid", which they believe can be used as a type of fountain of youth.
