中国深圳郊外的龙华新区，有一处大型职业介绍所“三和人才市场”。 周围小巷内，残破建筑物林立，廉价网吧、旅馆、杂货店等百余家店铺鳞次栉比。众多年轻人或在网吧内瞌睡，或露宿街头。 本片在绚丽奢华的中国硅谷-深圳，倾听从社会底层支撑着制造业大国的人们的心声，关注在希望和绝望之间挣扎的年轻打工者们的现实。(kamonka)

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.
