The Cave 2005
A group of scientists explores the secret forests of Romania and discovers a hidden cave. They inform American researchers, believing the cave may belong to a new ecosystem. Divers Jack and Tyler, among the world’s best, come equipped with a special diving snorkel allowing them to stay underwater for 24 hours. A massive explosion traps the dive team in the cave, leading the two brothers, along with Charlie and Buchanan, on a challenging 24-hour adventure. However, what they discover inside the cave is far from friendly.
