On the film front, overview is as is as follows:
Deep in the Romanian forest, a team of scientists stumbles upon the ruins of a 13th century Abbey. On further inspection, they make a startling discovery - the Abbey is built over the entrance to a giant underground cave system. Local biologists believe the cave could be home to an undiscovered eco-system, so they hire a group of American cave-explorers to help them investigate its depths.
