Hong Kong, 1996. Beneath the neon lights of Causeway Bay lurked the city’s deepest shadows. Chen Haonan, the police academy’s top graduate, was assigned an impossible mission: infiltrate the Hung Hing Society, get close to its boss, Jiang Tiansheng, and gather enough evidence to bring down the entire gang.
Starting out as a street punk, he earned his brothers’ trust with his fists and his loyalty. Shan Ji, Da Tian’er, Bao Pi, Chao Pi: these young men had “brotherhood” etched into their bones, and with them, he found another kind of truth amid all the lies.
But as his undercover mission entered its fifth year, as Boss B’s entire family was wiped out, his girlfriend Xiao Jieba was murdered, and his brothers fell one by one, Chen Haonan realized there was no way back from the line between the law and the underworld. The police suspected he had turned traitor, the gang demanded he prove his loyalty with blood, and his conscience interrogated him night after night:
Who are you, really?
