The mundane existence of a product liability evaluator and insomniac, who is addicted to self-
help groups, is turned upside down when he meets a sado-masochistic anarchist who is
secretly plotting to overthrow civilization. As their friendship grows, they become increasingly
involved in a secret society of "fight clubs" where men act out their aggressions and violently
beat one another to a pulp. In the meantime, the evaluator falls in love with a woman who is
also addicted to self-help groups, but is unable to act on his desire for her.
