A bulldozing disaster movie with "Men in Black" star Tommy Lee Jones as a crumpled-looking Emergency Rescue Bloke who finds himself in the hot seat when trouble erupts in Los Angeles. A heaving, pulsating mass of molten lava is threatening to engulf the city and it's up to Jones, with a little help from sexy scientist Anne Heche, to cool things down and save the usual assortment of terrified citizens from a fiery end. Explosively entertaining.
