S1·E39 Episode 39

After drunkenly composing a poem hinting at rebellion, Song Jiang was reported by Huang Wenbing to Prefect Cai Jiu and arrested. Dai Zong warned Song Jiang and advised him to feign madness, which Song Jiang did convincingly, even enduring extreme humiliation. Though Cai Jiu was nearly deceived, Huang Wenbing accused Song Jiang of pretending, leading to renewed interrogation, brutal torture, and imprisonment in a death cell. Cai Jiu sent Dai Zong to deliver a report to the capital. En route, Dai Zong was captured near Liangshan, the letter seized, and Wu Yong devised a plan to intercept the reply and rescue Song Jiang.
