Overview:Poor young Ma Zhijie lent his address and mistakenly received a drug package. Under the deception and misleading of the defense lawyer, he admitted to the drug trafficking charge. The former detective prosecutor Huo Zihao (played by Donnie Yen) used his police sense and persistence to investigate this unjust case despite violating regulations, and uncovered the true nature of the defense lawyer team through meticulous investigation. Under the obstruction of evil forces such as O'Brien (played by Zhang Zhilin), Huo Zihao bravely overcame difficulties and set traps, successfully restored the truth and brought the real criminals to justice, upholding the dignity of the law and preventing a ruthless miscarriage of justice.
