Just after the Anti-Japanese War, the liaison station was exposed and was besieged by the Hangcheng Station of the military command.
Lu Ru took Mi Lan with her on a bicycle and fled in the rain; the enemy's truck was chasing her. Mi Lan was ten months pregnant and was about to give birth; she rolled down the road in order not to injure Lu Ru. She climbed one kilometer to a ruined temple to take shelter from the rain and gave birth to her son.
Zhou Qi went to Linpu to find a midwife and came to a ruined temple to take shelter from the rain. Mi Lan gave her son to Zhou Qi to raise and named him Zheng. She gave Zhou Qi two letters and half a jade comb, one to send to her father, and one to keep Zhou Zheng's identity certificate from now on. Zhou Qi's wife Fang Xianfen also gave birth to a son that day, named Rong.
The enemy found Mi Lan and she died; the enemy searched for her son and the midwife betrayed him. The enemy found Fang Xianfen and forced her to hand over Zhou Zheng, Zhou Qi's old father. They replaced Zhou Zheng with Zhou Rong and handed it over to the enemy. Zhou Qi wanted to snatch his son back but died under the gun. In 1953, Lu Ruchao returned to serve as the deputy director of the Shaoxing Public Security Bureau, responsible for searching for hidden spies and interrogating. In order to upset his mood, the enemy created various rumors and provoked his relationship with Fang Xianfen. He misunderstood Fang Xianfen and mistakenly wanted to arrest Fang Xianfen publicly. In the end, the truth came out. Lu Ru was unwilling to apologize to Fang Xianfen because of his face; Zhou Zheng was unwilling to recognize him as his biological father. No matter Fang Xianfen tried to persuade him, Zhou Zheng refused to listen. Later, Lu Ru got kidney disease and needed a kidney transplant, but there was no original kidney. In the end, Xianfen accompanied Zhou Zheng to remove the kidney, without leaving her name. Lu Ru was discharged from the hospital and tried every means to find out about the kidney donor; when he learned that it was Zhou Zheng, he regretted it. Finally took the initiative to go to Fang Xianfen's home...
