这是一部以枪为主角的电影。情节都是透过手枪的角度表现出来。手枪由菲佣的手中传到尼泊尔青年那里，然后再由古惑仔交给了妓女，接着在白领、孩子、渔夫等人的手中传递着，每一个生命的结交都见证了香港光怪陆离、乌烟瘴气的人生百态。枪成为了一根纽带，它本不会杀人，但代表的是一种控制的权力，一经落入人手中就有了生命。枪从旺角的公厕游走到长洲再偷渡到深圳，所有的故事看似松散，但都一连串的发生了，枪是唯一的见证。

这是本导的第一部美国片，背景在1978年的波士顿，剧情围绕一座军火交易的仓库展开，交易出错，局势也变得越来越糟。

American Guns is a reality television series that airs on the Discovery Channel. The series centers on the Wyatt Family at Gunsmoke Guns, located in Wheat Ridge, Colorado; which specialize in gun manufacture, trade, customization, and instruction. The Wyatts are your typical suburban family... who just happen to own one of the premiere firearms facilities in the world. Rich Wyatt and his wife Renee own Gunsmoke, located outside Denver, Colorado, where they buy, sell and trade guns — from hand cannons to hunting rifles. And if you don't see what you want, they'll build one for you — from nothing more than a block of metal. Gunsmoke has the largest and most experienced group of gunsmiths in the state. When the Wyatts aren't building or selling guns, they're shooting them. No gun leaves their shop without being test fired by the family first. They — and the one-of-a-kind and historic guns they make and sell — are featured in AMERICAN GUNS.
