Cliff Spab and his friend Joe Dice go out one evening to buy beer from a convenience store, where a group of armed, masked terrorists take them and three other people hostage. The terrorists, who call themselves S.P.L.I.T. Image, have a video camera with which they tape their hostages' every word and action. S.P.L.I.T. Image's only demand is that their broadcasts be televised live on worldwide television, or else the hostages will be killed. The terrorists make good on the said threat by killing two hostages. Cliff, Joe, and teenager Wendy Pfister are the only surviving captives. Cliff eventually becomes indifferent to being killed. While being filmed, he demonstrates his new-found nihilistic world-view in an improvised monologue in which he repeatedly asks, "So Fucking What?". The coverage of this makes Cliff a media icon.

After 36 days of captivity, Joe manages to kill one of the terrorists. In the ensuing shoot out, Cliff shoots his way to freedom, taking a bullet in the shoulder while Joe is killed. Despite Joe's demise, Cliff is branded a hero for saving Wendy and killing the terrorists. He is picked up from the hospital by his brother Scott. He is welcomed awkwardly by his domineering father and weak-willed mother.

Back on the street, Cliff finds his life changed forever by the convenience store incident. His line – abbreviated as S.F.W. – is on banners, newspapers, CDs, and billboard advertisements. At Burger Boy, the fast-food restaurant where he works, Cliff finds his name and image posted alongside a "Special $.36 Spaburger" (named after him), being marketed in commemoration of his 36 days in captivity.

Cliff visits Joe's older sister Monica. She resents the media idolization directed at Cliff, while Joe has gotten neither sympathy nor attention. Cliff eventually has sex with Monica. The following morning, Cliff, who is disenchanted with the reporters camped on his front lawn, moves out. He visits another friend, Morrow Streeter, who lets Cliff hide out at the elegant home of his lawyer sister Janet. She advises Cliff to exploit his notoriety for personal gain. Lacking in any sense of purpose, Cliff hitchhikes out of town. He gets a ride with a couple, who idolize him. Cliff eventually stops fleeing from the journalists following him; he hosts a videoclip show, holds press conferences and makes public appearances.

More than anything, Cliff aspires to reunite with Wendy, but her parents will not let him. Wendy eventually visits him. They evade the media and revisit the convenience store, which has been closed down and boarded up as a crime scene. Wendy tells Cliff that it might be turned into a memorial park. The two later have sex.

Days later, Cliff and Wendy make a public appearance at a high school. They receive a standing ovation from a crowd of adoring students, who chant "So Fucking What!" One student, Barbara "Babs" Wyler, does not join in the cheering. After sitting in angry silence, Babs takes a gun from her book bag and stands up. With a yell of "Everything matters!" she fires on Cliff and Wendy, seriously wounding them both. Media attention switches to Babs as she is arrested, booked, and indicted for attempted murder. Her line of "Everything matters" becomes the new public catchphrase, replacing Cliff's "S.F.W.". It represents a less-disaffected philosophy than the one Cliff supposedly believes in, but it becomes equally popular. Reporters and other media people cannot stop talking about Babs' actions. Sharing their own hospital ward, the recovering Cliff and Wendy decide to get married.
