It deals with American bombardier John Yossarian.  Yossarian is stationed on the Italian island of Pianosa during [[World War II]].  He attempts to get out of flying more combat missions by pretending to be crazy.  The problem is, only a sane man would want to get out of combat, therefore Yossarian cannot be considered crazy.

The novel is notable for its staggered chronology, and the fact that each chapter is named after and follows one of the large cast of characters.  Heller uses the staggered chronology to slowly reveal more background to Yossarian's antics which, while seeming silly or insane at first, end up evoking horror.

The term "Catch-22" has entered popular language to mean an unwinnable situation.

The term "Catch-22" has entered popular language to mean an unwinnable situation.  More specifically, a catch-22 is a situtation in which a desirable outcome has two conditions precedent, one of which rules out the other, so that the desirable outcome can never be attained.  A catch-22 is thus similar, but not identical, to a [[deadlock]], in which two or more events are conditions precedent to one another.
