关永山期待着徐德海告诉他身边潜伏的卧底身份，为避免被人察觉，他让其他人远离，所以他们的对话没引起任何关注。关永山绝不会透露，是徐德海对这个人下手。只有徐德海披露他的姓名，才有机会和新月重聚。关永山恨不得将新月的照片搬出来，徐德海竟也认出她，拿过关永山的钢笔，掌握了宝贵的笔和纸。但徐德海却毒舌地写下了“卑鄙”这两个字，他瞬间辨出照片是伪造的，编造得太不精巧了。于是徐德海只得选择自尽，关永山怒不可遏，命令将徐德海的尸体扔进河里。像他这样陷入黑暗的人，还有很多很多。
吴若男当即下令暂停对余春羊的搜捕，回收部队。她知道徐德海殉职的消息后，内心十分痛苦，懊悔不及，后悔没有及时通知他们撤离。如果有一天她也像徐德海和顾曼丽一样成为牺牲品，那么她希望陈浅能够把他们没有完成的使命坚决地完成下去。徐德海曾经说过：他们都等待着光明。
谢冬天感到吴若男的最近变化让人摸不着头脑，分不清她是想帮忙还是害人。吴若男却断言自己早已不再爱陈浅了，她现在要帮忙的人是谢冬天。吴若男精心策划了一次突击行动，结果让余春羊和接头的共产党人均遭到擒获，有力棋子之一就是骆国栋。然而，余春羊来到交接房间后却猛地翻过窗户逃走，使吴若男气得七窍生烟，急忙去找骆国栋，结果发现他也消失得无影无踪。于是吴若男让魏德敏重新审查爆破图纸，只见图纸竟然不翼而飞。骆国栋的妹妹也被绑架了，吴若男的计划全面失败。
骆国栋从余春羊救他的那一刻起，便选择了和他们一起战斗。今天，他们的计划终于开始。周队长救下了骆国栋的妹妹，兄妹俩紧急撤离。面对军统的追击，余春羊和周队长无力抵抗，幸好陈浅出现救了他们。吴若男也追了上来，但被路上的障碍拦住了。她认定陈浅不会放弃外婆，便前往陈浅家探听消息。然而，到达时，只听到收音机里播放着樊梨花和薛平贵的故事，陈浅和外婆早已不见踪影。周队长已经带着外婆去了乡下的一所房子。外婆一直嚷嚷着要见孙媳妇，余春羊赶紧带着礼物前往，但她睡着了。周队长毫不照顾地坐在她们身旁，陈浅一遍又一遍地用眼神向他示意，最后他以买鸡为借口离开。余春羊和陈浅恍如二人世界般坐在院子里，已经很久没有这样单独相处了。余春羊谈起曾被徐德海救助的事情。当时饥荒肆虐，她身旁只有亲人的尸体。徐德海给她提供了食物，但她觉得这是背叛，始终不肯接受。徐德海的开导使她渐渐释然。余春羊说，她将和陈浅共同向组织申请结婚，成为老陈家的媳妇。 she snuggled into Chen Qian’s arms. Grandmother just woke up and praised her good looks repeatedly.
Madam Guan saw the letter left by Yu Chunyang and perhaps had guessed her true identity. Yu Chunyang revealed the truth about her adoptive mother's death, and it was up to Madam Guan to decide her future path. Regardless of her choice, Yu Chunyang would fully support her. Wu Ruonan wanted to continue with Guan Yongshan's plan to darken Chongqing. The liberation army was approaching Chongqing and would enter the city tomorrow. All communications within the city were cut off, and the situation was becoming increasingly chaotic.
Madam Guan arranged to meet Yu Chunyang and thanked her for being genuinely kind to her. She couldn't control the rest of the situation, but she revealed that she had overheard Guan Yongshan saying he was going to gather workers in the power plant and destroy them.
