Episode 19 recap: Shen Jin Zhen was betrayed and captured by Li Cheng Da.

Li Cheng Da reported to Kang Shao Jie that Shen Jin Zhen was a member of the counterintelligence team. Kang Shao Jie sent people to Shen's home, the train station, and the dock to capture Shen Jin Zhen. Wei Ruo Lai hid nearby and overheard everything clearly.Lin Qiao Song personally led a team to Shen Tu Nan's house to make an arrest, and Su Ci Shu couldn't stop him, so he had to let it happen. Wei Ruo Lai witnessed Li Cheng Da being transferred to the Licha Hotel. He booked a room in the hotel, but he didn't know which room Li Cheng Da was staying in. He called each room to confirm and finally figured out that Li Cheng Da was in Room 605.

Kang Shao Jie and his men arrived at the Licha Hotel overnight. He immediately took out ten gold bars and forced Li Cheng Da to reveal the underground party that wanted to kill him. Li Cheng Da was worried that he would be silenced by Kang Shao Jie after revealing the truth, so he insisted on speaking with Yu Shi Qing. Kang Shao Jie reluctantly dialed Yu Shi Qing's phone.

Li Cheng Da confessed that Shen Jin Zhen was the one who assassinated him last night and that she was a member of the counterintelligence team. He mentioned that she had a special fragrance on her body, which was a mixture of an Italian brand shampoo and shower gel that Mrs. Yu had given to Shen Jin Zhen.

Li Cheng Da used to run a perfume shop, so he had some knowledge about fragrances. Yu Shi Qing hurriedly went to verify the situation with his wife. Lin Qiao Song also smelled a faint fragrance when he entered Li Cheng Da's ward last night. Mrs. Yu had two sets of Italian imported shampoo and shower gel. She gave one set to Shen Tu Nan's wife, Su Ci Shu, and kept one set for herself. Kang Shao Jie ordered the arrest of Shen Jin Zhen.

Li Cheng Da wanted to leave with the gold bars, but Kang Shao Jie insisted on capturing Shen Jin Zhen first. Li Cheng Da could only wait patiently. Wei Ruo Lai and Lin Qiao Song took the detective team to the train station and the dock to capture Shen Jin Zhen. Wei Ruo Lai was worried for Shen Jin Zhen and secretly listened to the phone in Room 605.

Shen Jin Zhen was waiting at the train station when the station staff suddenly received a notification from the detective team to thoroughly check all passengers. The station made a public announcement that the train to Suzhou was delayed. Shen Jin Zhen became worried that the situation had changed and felt uneasy. Kang Shao Jie knew that Mr. Song supported Shen Tu Nan, so he didn't dare to provoke Shen Tu Nan. He ordered his men in Room 605 to silence Li Cheng Da. Wei Ruo Lai heard everything clearly through the phone.

Knowing that his chances of survival were slim, Li Cheng Da took advantage of the distraction and grabbed the person's gun, shooting him on the spot. The sound of the gunshot frightened the guests in the Licha Hotel, and they scattered in panic. Li Cheng Da seized the opportunity, took the gold bars, and escaped. Wei Ruo Lai witnessed everything. The train slowly arrived at the station, and just as Shen Jin Zhen reached the platform, she saw the detective team searching everywhere. Frightened, she quickly tried to hide and planned to board the train through the back door. However, she was caught red-handed by Lin Qiao Song. Shen Jin Zhen realized she couldn't escape and had to surrender.

Kang Shao Jie learned that Shen Jin Zhen had been captured and sent people to search her home. He personally interrogated Shen Jin Zhen in prison. Kang Shao Jie accused Shen Jin Zhen of assassinating Li Cheng Da, but she denied any involvement and vehemently distanced herself from the case. Kang Shao Jie pressured her relentlessly, but Shen Jin Zhen remained composed and provided convincing responses. Kang Shao Jie couldn't find any loopholes in her statements. He employed both threats and promises, even bringing up Shen Tu Nan and Su Ci Shu's lives being at stake, but Shen Jin Zhen seethed with anger.

Lin Qiao Song led a team to thoroughly search Shen's home but didn't find Shen Jin Zhen's gun. Frustrated, he left in disappointment. Su Ci Shu tried calling the Central Hotel in Nanjing, where Shen Tu Nan was staying, but no one answered the phone.

At that moment, Shen Tu Nan was waiting for an audience at Jiang's residence. Chiang Kai-shek had summoned important visitors overnight, so Shen Tu Nan had to patiently wait. Shen Jin Zhen wanted to confront Li Cheng Da face-to-face, but Kang Shao Jie had no idea of Li Cheng Da's whereabouts. He urged Shen Jin Zhen to confess to being a Communist Party member and promised lenient treatment for her family. Shen Jin Zhen retorted and scolded him for lacking principles, which infuriated Kang Shao Jie, who stormed out.

Wei Ruo Lai called Su Ci Shu and learned that Shen Jin Zhen had been captured and the detectives were searching their home. Su Ci Shu couldn't reach Shen Tu Nan. Wei Ruo Lai called the Nanjing Police Department and falsely reported that Huang Cong Yun planned to assassinate Shen Tu Nan, hoping the police would arrest Huang Cong Yun at the Central Hotel.

Kang Shao Jie feared that Shen Tu Nan would expose their deeds to Chiang Kai-shek and didn't dare to frame Shen Jin Zhen. He immediately dispatched people to search the city for Li Cheng Da and make him accuse Shen Jin Zhen.

After a long wait, Shen Tu Nan received a message from Ming Da conveying Chiang Kai-shek's orders to cancel all meetings for the day. Shen Tu Nan felt greatly disappointed. Huang Cong Yun learned about Shen Jin Zhen's capture and hurriedly came to inform Shen Tu Nan. Shen Tu Nan rushed back to Shanghai overnight.

Upon returning to Shanghai, Shen Tu Nan was briefed by Wei Ruo Lai about the events of the previous night. Huang Cong Yun suggested putting pressure on themselves by involving the weapons factory. The workers from the weapons factory staged a demonstration and protest at the Headquarters of the Garrison Command, adamantly demanding the release of Shen Jin Zhen. Shen Tu Nan, accompanied by Huang Cong Yun and Wei Ruo Lai, arrived shortly after. Kang Shao Jie invited Shen Tu Nan to his office, where Li Cheng Da pointed out Shen Jin Zhen as a member of the Communist Party's counterintelligence team. Shen Tu Nan desperately defended Shen Jin Zhen's innocence.
