This series chronicled the lives of Bodie and Doyle, top agents for Britain's CI5 (Criminal Intelligence 5), and their controller, George Cowley. The mandate of CI5 was to fight terrorism and similar high-profile crimes. Cowley, a hard ex-MI5 operative, hand-picked each of his men. Bodie was a cynical ex-SAS paratrooper and mercenary whose nature ran to controlled violence, while his partner, Doyle, came to CI5 from the regular police force, and was more of an open minded liberal. Their relationship was often contentious, but they were the top men in their field, and the ones to whom Cowley always assigned to the toughest cases.“说实在的，这人呐，活着就要知道惜福。你们俩现在都是生在福中，却还昏昏沉沉的，自己折腾自己。如今这年头想找爱情那可是难得，听陈姐一句劝，别太执拗了。你们俩这样，我这外人看在眼里都替你们干着急呢！”
