一颗奇怪的黑色流星在圣安吉洛镇附近坠毁，碎片散落在乡村。当风暴将这些碎片暴露在水中时，它们会成长为摩天大楼大小的巨石，然后倾覆并粉碎成数千块碎片，这些碎片本身会成长为巨石，并重复这一过程。路上的任何人都会被碾碎或变成人像。圣安吉洛的市民拼命地试图拯救自己和世界，使其免于不断蔓延的厄运。 A strange black meteor crashes near the town of San Angelo and litters the countryside with fragments. When a storm exposes these fragments to water, they grow into skyscraper-sized monoliths which then topple and shatter into thousands of pieces that grow into monoliths themselves and repeat the process. Any humans in the way are crushed or turned into human statues. The citizens of San Angelo desperately try to save themselves and the world from the spreading doom.
