二十世纪初期是西部的转型期,但著名的侦察员兼神枪手汤姆霍恩(史蒂夫.麦奎因饰)无视时代变迁,仍坚持个人的生存原则,以单枪匹马搜捕罪犯为生,最后被时代淘汰。本片根据汤姆.霍恩的自传改编,以冷峻手法表现一个没落西部英雄的形象,手法传统,故事清淡,但颇能捕捉到暴力与死亡的痛苦感觉。A renowned former army scout is hired by ranchers to hunt down rustlers but finds himself on trial for the murder of a boy when he carries out his job too well. Tom Horn finds that the simple skills he knows are of no help in dealing with the ambitions of ranchers and corrupt officials as progress marches over him and the old west.
