Influenced by Guy Ritchie's film, the role of the heroine, Irene Adler, was also expanded on during the show. Her love affair with Sherlock Holmes is one of the series' main storylines. She will be played by actress Lyanka Gryu. Kavun has also said he only plans to use the motives of the original stories, and will recreate the stories almost from scratch. The series will also assume that Watson's descriptions of the crimes have been embellished. Later he will try to adjust reality to his fantasies. As an example, Holmes' famous pipe will be replaced by cigarettes. Unlike most adaptations of Sherlock Holmes, the Sherlock in this adaptation is younger than Dr. Watson by 15 years.

马蒂（伍迪·哈里森 饰）和拉斯特（马修·麦康纳 饰）是一对合作多年的搭档，马蒂为人开朗圆滑，在警局的同事里很吃得开，而拉斯特则恰恰相反，他性格孤僻沉默寡言，沉浸在自己的世界中无法自拔。然而，令马蒂感到十分钦佩的是，拉斯特拥有极为敏锐强大的观察力、判断力和逻辑推理能力，许多疑难杂案一经他手，便能够被轻松化解。
尽管马蒂是唯一一个能够受得了拉斯特的人，但两人的合作和友谊却依然产生了无法弥补的裂缝，其原因要归结到1995年所发生的一起神秘古怪的宗教杀人案件之中。如今已经是2012年了，当早已不再联系的两人因为这起案件又重新走到一起之时，会有怎样的真相在等待着他们呢？

这是一部悬疑剧，虚构了四个拥有特殊技能的女人Susan、Millie、Lucy和Jean，她们曾帮助盟军提前取得二战胜利。
战争结束后，她们的生活渐渐平淡。一件凶杀案的发生，引起了她们的注意。
