Durden lives in a rundown mansion full of leaks and creaks, and, for lack of any other real life, Norton moves in with him. Durden and his zest for living amaze him. Before you know it, she and Durden become VERY loud and gymnastic lovers, almost tearing the house down at one point. Simply stated, they get together with a few other men, and beat the living hell out of each other in the basement of a local bar. It's a way to escape the rut of life and actually live like MEN should.
Word spreads about the club, and more start popping up all over the country.
Suddenly, it's like a manly whoop-ass cult. But, then, the fighting isn't quite enough, so Durden starts pulling pranks. That's where the narrator begins to realize that Durden may not be all there. But this thing is so much more than that. On the surface, it's one of the textbook examples of director David Fincher's unique camera eye.
