When Guo Baifei, Jiang Xiwen and Liu Li first came out of school more than ten years ago, they had a deep relationship with Sheriff Luo Youbang's four apprentices. During an operation three years ago, Bang was shot dead by bandits and was seriously injured and fell unconscious, and Wen blamed Yu Fei, and his friends have since parted ways. 　　In the city there is a young girl dismemberment murder case, the victim is related to the human trafficking syndicate, Wen from the Intelligence Bureau is responsible for investigating the syndicate criminal evidence, and Fei of the Serious Crime Unit is responsible for tracking down the murderer, and Probationary Inspector Wan Jiali is sent to infiltrate the criminal syndicate. Fei and Wen coincidentally received mysterious mobile phone messages one after another, prompting clues to the murder, and the superiors merged the two groups to form the Mysterious Information Intelligence Bureau (ASIB). Led by Fei and Wen, ASIB works together to dismantle these mysterious messages that seem to come from the future and solve the bizarre murder case. 　　The message is mysterious and cannot be explained scientifically. Who sent the message? By the future man? Or is it an unknown force of nature? Is the other party friend or foe?
