This is not a film about gun control. It is a film about the fearful heart and soul of the United States, and the 280 million Americans lucky enough to have the right to a constitutionally protected Uzi. From a look at the Columbine High School security camera tapes to the home of Oscar-winning NRA President Charlton Heston, from a young man who makes homemade napalm with The Anarchist's Cookbook to the murder of a six-year-old girl by another six-year-old. Bowling for Columbine is a journey through the US, through our past, hoping to discover why our pursuit of happiness is so riddled with violence.

Many times during his presidency, Lyndon B. Johnson said that ultimate victory in the Vietnam War depended upon the U.S. military winning the "hearts and minds" of the Vietnamese people. Filmmaker Peter Davis uses Johnson's phrase in an ironic context in this anti-war documentary, filmed and released while the Vietnam War was still under way, juxtaposing interviews with military figures like U.S. Army Chief of Staff William C. Westmoreland with shocking scenes of violence and brutality.

Clips from assorted television programs, B-movies, commercials, music performances, newsreels, bloopers, satirical short films and promotional and government films of the 1950s and 1960s are intercut together to tell a single story of various creatures and societal ills attacking American cities.
