Peter Stenning (Edward Judd) is a depressed British reporter who gets by with the help of his friend, veteran journalist Bill Maguire (Leo McKern). Along with weather forecaster Jeannie Craig (Janet Munro), Peter and Bill discover that simultaneous U.S. and Russian nuclear explosions have drastically altered the earth's rotation. Fires and earthquakes ravage cities all over the world, and chaos and sickness descend upon the frightened survivors as they try to put the planet back on its axis.
