After a personal tragedy, Sarah joins her friends on a caving expedition in the Appalachian Mountains. But when a rockfall traps them deep underground, their adventure turns into a nightmare. As they search for a way out, the group discovers they are not alone—lurking in the darkness are savage, cave-dwelling creatures. With rising tension and dwindling trust, the women must fight to survive against both the predators and each other.

Pacing Verdict
The screenplay establishes a masterful, escalating rhythm that builds from character-driven dread to relentless survival horror. The first act expertly balances dialogue and tension to establish relationships and trauma, while the descent into the cave triggers a near-perfect, breathless acceleration of action and terror with minimal lulls. The only minor deduction comes from a slight compression in the final escape sequence, which rushes Sarah's full psychological transformation compared to the meticulously paced earlier horrors.
