不久的未来，毒品泛滥已经失去控制，一种极易上瘾的非法药品“D药丸”在美国境内流行，政府当局只好利用高科技监视系统对抗失控的局面。卧底的缉毒探员弗瑞德（基努•里维斯 饰）化名巴布•亚特，试图追踪毒品来源，这样，他与小毒贩唐娜•霍桑（薇诺娜•瑞德饰）、吸毒者吉姆•贝芮斯（小罗伯特•唐尼饰）、厄尼•洛克曼（伍迪•哈里逊饰）、查尔斯•费克（罗瑞•考克兰饰）等人住在一起。但实际上，弗瑞德也被“D药丸”的毒瘾深深吸引。随着毒瘾越来越深，他逐渐模糊现实与虚假间的界线，失去神智的弗瑞德，不断追寻大毒枭的隐藏之处，毫不知情自己一直置身于幕后黑手的摆弄。In a totalitarian society in a near future, the undercover detective Bob Archor is working with a small time group of drug users trying to reach the big distributors of a brain-damaging drug called Substance D. His assignment is promoted by the recovery center New Path Corporation, and when Bob begins to lose his own identity and have schizophrenic behavior, he is submitted to tests to check his mental conditions.
