"Super Detective" depicts two close friends, Chen Yixian (played by Kwok Chun-an) and Fong Chi-keung (played by Liu Ximing), who were admitted to the police academy together and were later assigned to the same unit to serve as EEE.　　Johnson & Johnson is kind and has no scheming, but he is principled and unwilling to follow the crowd, so he has been repeatedly rejected by his colleagues in the bureau. On the contrary, his friend Xian is smart, skillful, scheming, jealous, and unscrupulous for fame and fortune, so he is very valued by his colleagues and superiors.　　Once, Qiang was injured in an arrest operation, and the bullet pierced between his heart and lungs, miraculously surviving, but since then he has developed "superpowers". Even Qiang himself doesn't quite understand why he can "replace his hands with his eyes", "change his shape" or "electromagnetic effect". Fortunately, there is a strange person, Shen Jie (played by Gu Feng), who teaches him to control his superpowers.　　Qiang and Hyun were thrilled in an operation to arrest gangsters, Hyun was accidentally wounded by a gunshot, and Qiang was in a crisis, unknowingly using superpowers to arrest gangsters, and Qiang was promoted.　　Ruan Wen was originally Hyun's girlfriend, and she stayed by Hyun's side wholeheartedly, but Hyun snubbed Ruan Wen many times because of selfishness, which made Ruan Wen feel lost. Qiang has had a crush on Wen since he was a child, and he gives encouragement from time to time; Wen is not valued by Xian, and she is looking for a strong confidant, and the love between the two gradually grows.　　Hyun is jealous of Qiang's promotion, and Wen proposes to break up with Hyun again, and confesses that she is in love with Hyun, which makes Hyun even more resentful. Qiang was assigned as a bait by the chief, and in the danger of life, he used his superpowers to capture the gangsters, at this time, the master Shilong (played by Wang Longwei) appeared, and the gangsters were wiped out with high skills.　　Xian witnessed Shi Long's superpowers, but he told Qiang, Qiang was careless for a while, and told his son that he had superpowers; Xian Nai asked to see Shen Jie, but Shen Jie saw through Xian's improper mind at a glance and advised him not to approach Shilong, so as not to stray into the Demon Dao.　　But Xian did not go well in his official business, and happened to meet Shi Long, who lured him to be an apprentice, and Xian became famous and wealthy, and began to learn superpowers from Shi Long.　　Ma Feng'er (played by Peng Jiali) met Qiang's mother Guan Jinghong (played by Su Xingxuan) by chance, and the two fell in love. Feng'er is tricky and lively, and often plays tricks on Qiang at first, but gradually understands Qiang's loyalty, and gradually falls in love with Qiang. Xian learned about Feng'er's illustrious background and used Qiang to get acquainted with Feng'er, and Xian gradually developed feelings for Feng'er, but Feng'er had no feelings for Xian, only for Qiang. Although Wen was repeatedly harassed by Feng'er's words and actions, she always endured it silently.　　Hyun and Keung are divided into two different groups to fight crime together. However, the leaders of the two groups did not agree, resulting in the two groups of people grabbing merit everywhere; During the joint investigation of a major criminal case, Shi Long was involved in it, and Long wanted to threaten Hyun to commit murder, and since then, Hyun has been trapped in the devil's path and cannot extricate himself.　　Qiang's master, Shen Jie, was originally a mainland public security officer, and came to Hong Kong to arrest the superpower master Shi Long and returned to the mainland for trial. Under Qiang's unrelenting investigation, the truth was gradually unraveled, just as he had the evidence of the crime, but was intercepted by Shi Long, and the dragon was about to poison Qiang, but fortunately Shen Jie arrived, although he beat the dragon away, he was seriously injured. Feng'er also sacrificed her life to save the strong.　　Xian is afraid that his deeds will be exposed, so he continues to kill people with superpowers, and designs to frame Qiang, although Qiang knows that Xian is evil, but he cares about his friendship and is unwilling to break with Xian.　　Long saw that Xian's deeds were exposed, thinking that Xian had no use value, and wanted to kill Xian, but fortunately he was rescued by Qiang and Jie. Hyun did not repent, but instead realized a deeper magic, eliminated the stone dragon, and continued to do evil.　　Unable to bear it, he deliberately sent Wen to the United States and sent Red back to the countryside, and after having no worries, he decided to start a life-and-death duel with Hyun ......
