故事承接第一季《黑爵士一世》，讲述六十年后的都铎王朝伊丽莎白一世时期的故事。金雀花王朝此时已经灭亡，由伊丽莎白一世（米兰达·理查森 Miranda Richardson 饰）继承王位。而这位像她的家族一样疯狂的女王，虽然性感诱人，却又极为情绪化。她一直都在寻找理想中的丈夫。伊丽莎白一世拥有一个最具权威的宫廷弄臣埃德蒙·黑爵士（罗温·艾金森 Rowan Atkinson 饰），他是《黑爵士一世》中埃德蒙王子的曾孙。
　　此次，埃德蒙摇身一变成为愤世嫉俗又充满智慧的冷酷朝臣，欲借娶伊丽莎白一世而篡夺王位。爱耍小聪明的农民鲍德里克（托尼·罗宾逊 Tony Robinson饰）和愚蠢的贵族珀西（蒂姆·麦克纳尼 Tim McInnerny饰），再次协助埃德蒙展开啼笑皆非的夺权计划。然而，伊丽莎白一世的得力助手曼彻特主教（斯蒂芬·弗雷 Stephen Fry 饰）一直在忠心耿耿的暗中辅佐她，免于王位落入埃德蒙之手。

　　Helen West is a crown prosecutor who cares about people in the criminal justice system and seeks to ensure that justice is done. She has a particular interest in women's issues and has to put up with her somewhat odd superior and his cleanliness phobia. She recognizes that it's the role of the police to find the evidence but also feels it warranted to occasionally investigate matters herself. Unmarried, she is also in a relationship with Chief Supt. Bailey, though neither seem to be able to make up their minds about their futures or what they want to get out of life.

　　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.
