An insomnia-stricken corporate drone (Edward Norton) meets roguish rebel Tyler Durden (Brad Pitt) and together they form a cathartic but brutal underground society where men fight each other freely. But the line between reality and sleepless haze starts to really blur when propagandist Durden transforms Fight Club from a group of men rebelling against conformity into a nihilistic cult with greater malice in store. Helena Bonham Carter co-stars.
