Later that night, the anaconda appears and attacks the boat crew. When Serone attempts to capture the snake alive, it coils around Gary and begins to crush him. Terri attempts to save Gary by shooting the anaconda, but Serone knocks the gun out of her hands, allowing the snake to kill and devour Gary. Denise mourns the loss of her boyfriend. The survivors overcome Serone and tie him up for punishment. The next day, the boat becomes stuck at a waterfall, requiring Terri, Danny, and Westridge to enter the water to winch it loose. Denise confronts Serone and attempts to kill him in revenge for Gary's death, but he strangles her to death with his legs before dumping her corpse into the river.
