Soon after, they destroyed the New York city. It is then that NASA found out that a huge asteroid, as the size of Texas, is headed towards Earth. If it is not destroyed soon, then the complete Earth would be wiped out of existence. They decide to use the nuclear warhead to destroy that asteroid from inside. The only man to do this is an oil driller named Harry Stamper. How does Harry form his team and blow the asteroid forms the rest of the story.
