In a future world, emotions are outlawed, with the population kept under control with compulsory use of sedatives, ruthlessly enforced by gun-toting `clerics'. When one of these law enforcers stops taking his own drugs, he falls in with an underground group of rebels fighting to overthrow the system. Sci-fi adventure, starring Christian Bale, Emily Watson, Taye Diggs, Angus MacFadyen and Sean Bean
