An elite secret Tokyo Police action squad is on an extended mission in rough terrain when one of it's members goes crazy from stress/exhaustion and begins firing his assault rifle at everyone. He is shot and killed by one of the group, which go on to complete the mission. The unit is broken up, and the shooter is assigned to the created-just-for-him section, "Special Missions." Police higher-ups hope Police Inspector Sugishita Ukyo will tire of having nothing to do and resign. To their dismay, this Anglophile detective looks into closed and current cases and begins to solve them via his "bad habit" of fixing on inconsistencies in the case. One day, disgraced Police Sergeant Kameyama Kaoru is assigned to "Special Missions" by mistake, and "The Partners" duo is born. The cool and collected Sugishita and his action-oriented partner clash with Investigation Section One frequently, though the partners usually hand the solved case over to them for credit. Interesting stories, memorable villains,and sharp banter make this TV worth watching, for 14 seasons!
