Zheng Shaoyang is an elite criminal detective in the police world. He has repeatedly solved major cases and has achieved a small success in his career. However, his performance in interpersonal relationships is not very good. He has lived for thirty years but only has two friends. Qingmei is tabloid reporter Zhu Tianya, who neglected her good medical career to become the editor of a gossip magazine; her sweetheart is Wang Zihan, who spent a lot of time and money studying abroad, but is determined to make a life-long career in dancing. Although these two friends seem a little unreliable, they are quite useful at critical times, especially when Zheng Shaoyang encounters some bizarre cases that cannot be explained by normal logic. Life is an adventure, and some experiences can only be regarded as legends even if they are true.
