Descent

When the Earth's crust cracks open, unleashing a torrent of molten lava, a team of scientists must venture into the heart of the volcano to find a way to stop the impending disaster. Led by Luke Perry as Dr. Deschanel, they face treacherous underground tunnels and personal demons in their quest for survival. As they navigate the treacherous Ring of Fire, they risk being burned alive by the very flames they seek to control. With science fiction thriller credentials that don't quite live up to its dramatic premise, "Descent" is a disaster movie that plummets headlong into chaos and destruction.
