Bai Yao, a genius of the Bai family, was falsely accused of being a traitor who defected to the Black Dragon Society and killed his compatriots. After the news of his "death" came, he was reviled by the public. His family, except for his mother, distanced themselves from him. In fact, he was an undercover agent carrying out the "Prairie Fire Plan" with his master Lin Tian, hiding in the dark disguised as a beggar. Lin Tian's daughter Lin Wanshang holds a life image recorder and gradually reveals the truth through live broadcast on the TV station. After a life-and-death pursuit, he teamed up with his grandfather Bai Qi, father Bai Yuan and other relatives to uncover the three ghost elders in the Martial Arts Department and eliminate the traitors in Haicheng. In the end, Bai Yao was avenged, and those who had scolded him in the past repented. He also returned to his family who were waiting for him with scars all over his body.
