A mountain RANGER's voice messages reveals that the girls are missing. Did they forget to call in? Or are they in trouble? CUT TO the rescue team outside the Boreham Caverns: there's DAN, the leader, with GREG, 22, and CATH, 27, working as volunteers. They head down into the caves, noting the dangerous outcroppings and sheer rockfaces. They emerge from the cave with no clues, glowering at Chief Deputy VAINES, who is pressured to get some kind of search party going. But where to start?

Suddenly, a woman staggers into the window of a roadhouse café, smearing it with blood. This is SARAH, one of the cavers! She collapses and is taken to the hospital, where Vaines and his younger partner, the female RIOS, try to question her. Rios tries the soft touch, but Sarah is clearly traumatized, hearing ‘click' sounds everywhere, fearing for her life ... and unable or unwilling to talk. Believing that Sarah's memory is the key to finding the others, Vaines finally takes over and decides to take Sarah with them into the caves. Her memory will certainly be jogged, and maybe she can help them locate the other lost girls before time runs out.

Sarah allows herself to be taken to the mines. She sits there, numb, totally shut down. Vaines, Rios, Dan, Greg, and Cath accompany her down in the creaky elevator, where Sarah gets more and more nervous. Realizing where she is going, she finally lashes out, screaming, "Don't go down! There's something down there!" but it's too late - they are halfway down into the caves. Sarah is restrained. They reach the bottom and begin looking for the lost girls as Sarah's fear becomes nearly overwhelming. Rios tries to soothe her, but down in the dark caves, with collapsing ceilings, drips and clicks and echoes everywhere ... it's very creepy. Dan watches Sarah's reaction and regrets allowing Vaines to bring her down.

Suddenly the group comes upon a horse skeleton on the floor. Claw marks on the walls. Sarah shrinks in fear. They then find a snaplight and boot - from a caver! When Cath shouts out for the girls, Sarah tries to smother her into silence. She admits that there are "creatures" down there. Then they find the body of a girl (REBECCA from the first film). Half of her face is missing; a rat slips out of her mouth. Should Sarah be considered a suspect?

The radios stop working, and the group is clearly lost. Dan and Cath veer off alone. When Cath is trapped after a ceiling collapse, Dan tries to calm her and promises to return, but he wonders if he'll ever see her again. He comes upon BETH's (from first film) smashed face while several feet away, Rios sees Holly's body, eviscerated. Dan can't believe Sarah would do that, and Rios points out the savageness of the wounds. Sarah dashes off alone into one of the honeycomb tunnels. In the distance, Greg screams. Sarah turns off her flashlight and ducks down, quiet, then traces a drip of water. Then Dan and Rios find the cavers' camcorder, which plays back the scenes of their laughter and fun. The replay shows them entering this very spot of the cave, seeing the animals' bones. Then the shadow of a CRAWLER is visible, and as Rios struggles to rewind it, a Crawler appears right before them, hisses ... and Rios drops the camcorder. As Dan fumbles about the sudden darkness for it, Sarah grabs Rios and covers her mouth just as a

Crawler appears, sniffing around. Sarah refuses to warn Dan. Dan finds the camera and lifts its

light just in time to see Sarah holding Rios - and then bam! He is attacked, eaten, but Sarah and Rios are safe as the Crawler drags Dan's body away. Rios is horrified that Sarah just let Dan die, but Sarah won't stay around to be scolded. She takes Dan's left-behind flares, flashlight, maps and tools and heads out. Rios follows, freaked out. CUT TO Cath, still trapped, hearing the sinister clicks, thinking Dan is approaching. But of course it's a Crawler, whom Cath manages to slam in the face with a sharp rock, dislodging the rest of the ceiling. As it falls, the Crawler is killed and Cath escapes before being buried. She scurries down the tunnels and finds herself in a Crawler Catacomb. Cath bumps into Greg. They are relieved to be together.

Meanwhile Vaines comes upon Dan's body and assumes Sarah killed him. He tries to contact Cath and Greg via the radio, but his message is barely audible. Cath and Greg keep running and come upon SAM's body (from the first film), dangling upside down from a rope, her innards chewed away. The duo is chased by Crawlers; Cath swings at it with her pick but is pulled down, and devoured. Meanwhile Sarah climbs and swims through numerous tunnels and poor Rios, out of her depth, struggles to keep up. Sarah risks her life to save Rios. The two women form a bond as they nearly drown, are decapitated, and chased by Crawlers. They struggle to find a way out. Rios records a last message on her phone for her little daughter while Sarah remembers hers (now dead). They have a narrow escape from a hungry Crawler.

In another part of the cave, Greg is attacked by two smaller Crawlers but is attacked by its MOTHER and eventually kills himself on his own whirring drill. CUT TO Vaines, who thinks he's being attacked by Crawlers but comes face to face with JUNO - one of the girls lost in the cave! She is filthy, feral, and up for a fight. Vaines still believes Sarah is to blame, and Juno (who remembers killing Beth) is disinclined to change his mind with the facts. But then Vaines catches sight of a Crawler and stares in utter disbelief. Juno kills it. Vaines now blames Sarah for leaving Juno and the others for dead. Juno senses the Crawlers advancing and attacks with her teeth. Then she grabs her pick and is about to strike in another direction when she comes fact to face with ... Sarah. They stare, frozen. Vaines then takes charge and ushers them to find out away. They four (with Rios) are the only ones left.

Then, as they try to escape, the ground gives way beneath Vaines's feet. The girls realize they have to leave him or be killed themselves, and seeing their choice, Vaines claps handcuffs around his own wrist to Sarah's. When the Crawlers, chewing on the dangling Vaines, threaten to bring down the whole group, they struggle for the keys without success. Finally Juno uses an axe to chop Vaines's arm off at the wrist. He falls, screaming, as the others tread carefully through the caves looking for a possible exit. The find the area, blood-drenched, where the Crawlers eat; there they are, chomping away. The three press on until they see an opening up above. Juno waits below while Sarah and Rios press their backs together and ‘walk' up the side. Sarah throws a rope for Juno, and hauls her up. But Juno is getting mauled from below, and she gives Sarah permission to go after Rios, who has found the cave opening, and safety.

But Sarah chooses to stay and help Juno fight off the Crawlers. They are about to be overrun by hundreds when they realize they still have Dan's gas detector, signaling a red alert for methane. Using a lighter, the girls ignite a fireball that rushes through the tunnels, killing everything (even them ...?) while Rios, out safely, calls for backup just as a Crawler attacks her, jaws open.
