John Yossarian is a bomber pilot in the United States Air Force during World War II. He becomes frustrated with the fact that thousands of people he has never met are trying to kill him. However, his real problem is not the enemy, but rather his own army that keeps increasing the number of missions. If Yossarian makes any attempt to evade his military duties, he will be in violation of "Catch-22", a hilarious, sinister, bureaucratic rule.
