Who's the Keyman (simplified Chinese: 我是大侦探; traditional Chinese: 我是大偵探; pinyin: Wǒ Shì Dà Zhēntàn) is a Chinese variety show produced by Hunan Television and Mango TV.[1] The show features the main cast of He Jiong, Deng Lun, as well as resident guests Han Xue, Wowkie Zhang, Ma Sichun and Leo Wu.[2]
The show is a remade version of Who's the Murderer.
In a prologue, the cast is introduced to the settings and suspects of a crime case for the new episode. The cast then chooses their role in the episode, as a particular suspect or the detective. Other than the detective, each person is given detailed information about the suspect they are portraying including their personalities, alibi, relationship to the victim and other suspects, history, criminal motive, etc. Every suspect can conceal information until explicitly questioned by other suspects or the detective, but only the keyman can lie. The gold keys are given to the cast members beforehand. If they vote correctly, they can keep the gold key. If not, they will have to return it.
In the final episode, all six cast members are detectives, and the keyman is hidden in the non-player characters. The players are separated into two teams, and the first two players with the higher number of gold keys are the team leaders. The two leaders will have to make a reasoning according to the conditions and clues, and they will help to identify the keyman. If the keyman is identified, each player will be awarded a gold key. Meanwhile, a gold key box is hidden in somewhere, the player who opens it will be awarded an additional gold key. The player who obtain the highest number of gold keys will be titled as "The Best Detective" (Chinese: 全能推理王).
