During the second half of World War II, a soldier named Yossarian is stationed with his Air Force squadron on the island of Pianosa, near the Italian coast in the Mediterranean Sea. The squadron is thrown thoughtlessly into brutal combat situations and bombing runs in which it is more important for the squadron members to capture good aerial photographs of explosions than to destroy their targets. Their colonels continually raise the number of missions that they are required to fly before being sent home, so that no one is ever sent home. Still, no one but Yossarian seems to realise that there is a war going on; everyone thinks he is crazy when he insists that millions of people are trying to kill him.
