Agent Hong Shisi was on a mission when she learned of the bizarre death of her sister, Hong Shanshan, under suspicious circumstances. Finding a vital clue in her sister’s belongings leading to the overseas “Jiuyou Prison”, Hong Shisi infiltrated the prison undercover.
On the surface, Jiuyou Prison holds only high-risk criminals, but it is secretly controlled by shadowy forces engaged in long-term illegal activities. Drawing on her professional training and sense of justice, Hong Shisi gathered key evidence against the prison’s criminal syndicate and gradually uncovered the truth.
Finally, with the joint operation of Interpol and domestic law enforcement, the criminal organization behind Jiuyou Prison was completely dismantled.
