日本最坏的家伙们

大学时代学习柔道的诸星要一（绫野刚 饰），凭借特长而被借调到北海道担任刑警。没有比赛的日子里，他终日负责无聊杂务，满腔的正义之情无处释放。在警署金牌刑警村井（皮埃尔泷 饰）的点拨下，一直以来非黑即白的诸星茅塞顿开，他大肆发展线人，狂刷积分，于是成为北海道道警中的得力干将。他与黑道大哥黑岩胜典（中村狮童 饰）、毒品贩子山边太郎（Young Dais 饰）等灰色地带人物称兄道弟，依靠他们收缴枪支以完成警署指标，甚至动用公家资金贩卖毒品、走私枪支。诸星满心以为自己在做正义之事，却不曾想早已离他的梦想越来越远…… 　　本片根据前北海道警察稻叶圭昭的真实事件改编。In this story of a good cop going rogue, we travel with Yoichi Moroboshi from his university student days to his becoming an ambitious detective on the beat who is using his brawn rather than brain to get what he wants and to where he wants to go. The lines between good and illegitimate are blurred as the detective gets closer to his assignments.
