Fight Club starts off with our nameless narrator held hostage with a gun in his mouth atop a building rigged with explosives set to go off at any moment. Yeah, The Baby-Sitters Club this ain't. Starting from this dire situation, our narrator decides to tell us how he got to this point.
It starts where most great stories start: testicular cancer support group. Even though our narrator attends a variety of support groups, he has no cancer. Just Issues. With a capital "I." Apparently, going to the support groups and looking certain death in the face helps our narrator overcome his insomnia. But then a problem walks in—a problem named Marla Singer. Our narrator can't sleep when Marla Singer's around. She exposes his lies.
On a business trip, our narrator takes a side trip to a nude beach where he makes a new friend: Tyler Durden. Tyler's kind of a hippie Zen philosopher type. When he gets home, our narrator discovers that his apartment has exploded. Hmmm, he probably shouldn't have left the oven on. Anyway, needing a place to stay, he crashes with Tyler Durden. They go out drinking and beat the crap out of each other in a bar parking lot. You know, guy stuff. From this fateful encounter, fight club is born.
