A ticking-time-bomb insomniac and a slippery soap salesman channel primal male aggression into a shocking new form of therapy. Their concept catches on, with underground "fight clubs" forming in every town, until an eccentric gets in the way and ignites an out-of-control spiral toward oblivion.

David Fincher created a masterpiece in this mind-bending psychological drama that features a star-studded cast with extraordinary twists.
