An unnamed narrator, sleepless and suffocating under the weight of his consumer-driven life, meets Tyler Durden, a charismatic soap salesman who lives by a completely different code. Together they form an underground fight club, a place where disaffected men can feel something real. But as the club grows into something far bigger and more dangerous, the narrator begins to lose his grip on what's real and what he's created—a psychological thriller about identity and masculinity.
