Decades after a rock church in communist Romania's Carpathians caved when an expedition caused a landslide and buried everyone, Dr. Nicolai's scientific team exploring the associated Templar Knights monster fighting-legend discovers a deep, flooded cave system and hires the brothers Jack and Tyler's brilliant divers team to explore it. Another explosion traps them, after finding a mysterious parasite turning all species carnivore, and later an independently evolved predator species. Jack may be infected and turning, but Tyler sticks with him, so the group splits, hunted by the monsters, which also fly.

Andrew Mason, one of the film's producers, says they hired some of the world's greatest cave divers as consultants in order to keep the movie as technically plausible as possible.

Goofs
Errors made by characters (possibly deliberate errors by the filmmakers):
Tyler jumps into the water, then grabs his mask and puts it on and begins swimming, but he fails to clear his mask by blowing the water out of it. Without clearing it, he wouldn't have been able to see a thing.
