In the play, Lin Mosheng is going to privately transport the template to * * *. Only to be stopped by Gu Jingjiang, the two finally took to the opposite side. Gu advised Lin Mosheng to write a surrender book to keep him and Ding Yiqing safe.

But for the sake of national justice, Lin Mosheng chose to destroy the template, and Gu Jingjiang's men killed Lin Mosheng by mistake. At this point, Lin Mo died, and Gu Jingjiang regretted it.

Without news of Lin Mosheng, Ding Yiqing risked his life to send a telegram to the organization, saying that Lin Mosheng would have an accident if he didn't come back. On the other hand, the national government asked Gu Jingjiang to hand over Ding Yiqing to the Chongqing government.

That night, Gu Jingjiang urged Ding Yiqing to go to Chongqing, and Ding Yiqing said that he would go home and prepare some clothes. Gu Jingjiang agreed, but said that the housekeeper Xu must be there. Ding Yiqing asked the housekeeper Xu at home. Finally, the housekeeper Xu told the truth of Lin Mosheng's sacrifice, and for so many years of friendship, Xu Shu was willing to help Ding Yiqing escape successfully.
