The earth has opened up and mankind must find out what is causing the destruction before it's too late in the one disaster film that offers no safe haven and no place to run to. An entire mountainside is transformed into a grinding field of rock, soil, and timber in a matter of minutes, and that's only the beginning of the chaos. As hikers run for their lives and ancient, monolithic trees are shredded into splinters, destruction sweeps across the landscape with no apparent cause, and no end in sight.
