After a pandemic flu has wiped out all but a few people, a pilot named Hig finds himself teamed up, for better or for worse, with Bangley, who is armed to the teeth and would rather shoot first and ask questions later. They have staked out a valley with a small suburban airport, with Hig warning people from the air that they should stay away. While Bangley is ruthless, Hig has a gentle nature, so they keep to themselves with Hig’s dog Jasper being his only real friend. It is a lonely and violent existence. When Hig hears a radio transmission from his plane, he must decide whether or not to risk everything to see if there is still some civilization out there.
