The "Hao Hao Hao" Detective Agency receives a commission to investigate the disappearance of Cheng Lala. Since Cheng Lala was last seen at the "1111 New Media Company" on Sanban Island, six members of the agency—Qi Wei, Zhang Yuqi, Li Yitong, Li Xueqin, Tian Xiwei, and Zhang Yifan—disguise themselves as new employees. The investigation progresses through various smaller cases and a major case that spans the entire season. Taking women' sensibility, empathy, gentleness, sensitivity and intelligence as the starting point, the series takes the audience through an immersive process of investigating the cases.
