The Cave (2005)

Synopsis
Terror lurks deep beneath the surface of the Earth in this thriller. While on a dig in a Romanian forest, a group of scientists make a startling find -- they find a huge abbey, dating back to the 13th Century, which was built over the entrance to a massive network of subterranean caves. Eager to learn what lurks within the caves, the scientists discover to their peril that a large part of the cave system is under water. Undeterred, the remaining scientists hire a team of American spelunkers who are trained in exploring underwater caves, led by brothers Jack (Cole Hauser) and Tyler (Eddie Cibrian). Armed with new high-tech SCUBA gear that allows them to stay under water for a full 24 hours, Jack, Tyler, and the rest of their crew dive in to investigate the caves, but a mishap traps them in a cavern beneath the surface, and they soon discover they are not alone, as strange and bloodthirsty creatures make their presence known. The Cave also stars Morris Chestnut, Rick Ravanello, Piper Perabo, and Lena Headey. ~ Mark Deming, All Movie Guide
