Plot

Two days after the first film, a traumatized and blood-covered Sarah escapes the cave system with amnesia. She is taken to a hospital, where the doctor finds that some of the blood on her is of the same blood type as Juno, one of her missing friends. Sheriff Vaines and his deputy Rios bring along the amnesiac Sarah and three pothole cave specialists – Dan, Greg, and Cath – to find the missing women. They are sent to the cave via an old mine shaft operated by an old man, Ed. The group discovers Rebecca's corpse near the entrance, causing Sarah to experience flashbacks of previous events before her escape. Vaines believes that she was responsible for the other women's disappearances. While crawling through a tunnel, Sarah suddenly attacks Vaines and Greg before fleeing.
