Los Angeles. It is perhaps best known as the entertainment capital of the world--a sun-kissed golden metropolis of glitz and glamour. To others it represents something very different. Millions more recognize The City of Angels as the unwilling epicenter of virtually every natural disaster--including earthquakes, firestorms and mudslides. Now the city which has become almost a byword for disaster is about to experience its most cataclysmic event ever, one that will ultimately test its ability to survive. A vent in the earth's crust has unleashed an incredible force of nature. The literally earth-shattering product: an erupting Volcano... and ground zero is L.A.'s famed La Brea Tar Pits. An unprepared Los Angeles is facing its worst nightmare as an endless stream of fiery, deadly lava insidiously creeps across traffic-choked streets while wreaking havoc below ground in the labyrinth of man-made natural tunnels.
