Greenland

All the media are abuzz with news of a comet approaching Earth, but civil engineer John Garrity is more concerned with saving his crumbling marriage. They have a neighbors' party planned for today, and while going to the supermarket to buy groceries, John suddenly receives a presidential message informing him and his family that they have been selected for safety in a secret bunker. At first, he doesn't pay attention, but soon the shockwave from the comet's first impact with Earth reaches their quiet suburb, and horrific images of destruction begin to appear on every TV channel. Getting into the car with his wife and son, under the bewildered gaze of his neighbors, John rushes to the airport, where those who received the messages are being loaded onto cargo planes.
