This movie tells about a team of scientists stumbles upon the ruins in a Romanian forest. Later, another group of scientists found the cave and starting to discover what is in the cave. They believe that inside the cave is an undiscovered ecosystem, and of course this can be a new discovery in science. So they hire professional cave explorers to investigate it depths.
Cole Hauser, also known as Jack and his brother Tyler (Eddie Cibrian) are seek for professional cave explorers who run a team of the top divers in the world. Along with the crack unit, Charlie (Piper Perabo) and Buchanan (Morris Chestnut), they begin the exploration through the cave. They named the front cave as "Titan Hall". Inside the cave, they not just found a new ecosystem, but also a new horrible species that lived in that place. The species cannot see, but they can detect motions, and they can fly. I like this movie. It really pumps up my adrenaline. The movie tells about where those species comes from. This movie is produce by Screen Gems and Lake Shore Entertainment. This is an old movie, but you should watch it.
