Episode 3 recap: Lin Mo is facing danger again.

Lin Mo used lime powder to temporarily blind Shama's eyes, narrowly escaping disaster. The security guards arrived and captured both of them. Director Daming already knew that someone intentionally triggered the fire alarm to create chaos. When Lin Mo was brought in, he angrily accused Lin Mo of causing significant property damage to the sanatorium. However, Lin Mo turned the tables and questioned him, asking if a human life was worth less than those properties, especially when Sakura had died.

Daming didn't want to waste time talking to Lin Mo and ordered him to be put into solitary confinement. Although Lin Mo didn't know what solitary confinement was like there, he knew it would be uncomfortable. He broke free from the security guards and rushed toward the main gate of the sanatorium. Several guards tried to stop him but were all knocked down by him. Just as Lin Mo was about to successfully escape, Shama suddenly flew over and quickly restrained Lin Mo by grabbing his neck. Shama used scissors to injure Lin Mo's nose.

Peng Xi reminded Daming that she had looked into Lin Mo's information and discovered that he was a private detective. However, Daming didn't care at all and said that even if the president came here, he would still have to listen to him. After saying that, he ordered Lin Mo to be locked up in the solitary confinement room. Lin Mo was locked inside an iron room, and the only opening was a small slot where meals were delivered. At first, Lin Mo endured it reluctantly, but later he couldn't help but throw things, shout, and kick the door with all his might. However, even if he shouted until he lost his voice, no one paid attention to him.

Half a month later, Lin Mo was released from solitary confinement, but he seemed like a completely different person. Daming stood on the third floor, observing him through the glass for a while. Seeing Lin Mo's vacant expression and curled up in a corner, he smiled and said to Peng Xi beside him, "He was right, wasn't he? No matter what kind of person they are, they all become like lambs to be slaughtered here."

After Daming finished speaking, Peng Xi reminded him that Shama was about to be released from solitary confinement. Shama was a very vengeful person, so she asked if they should separate the two individuals. However, Daming smiled and replied that he didn't want to change one patient for another just for the sake of a single patient.

An Song came to see Lin Mo, and Lin Mo knew he wanted to hear a story. So, he told his own childhood story and asked An Song to tell him Shama's story. An Song told Lin Mo that Shama was a professional Muay Thai fighter. When his wife eloped with someone else, he resorted to underground fighting. During one of his fights, he didn't follow the boss's instructions but ended up winning the match. However, this victory brought disaster to his entire family. Seeing his family being killed, An Song suffered a mental breakdown and became the way he is now.

An Song also informed Lin Mo that Shama would be released soon, and with his vengeful personality, he would definitely seek revenge on Lin Mo. Upon receiving this news, Lin Mo sought Nancy's help and asked her to keep away from Shama in the intensive care unit. Nancy conveyed his request to Daming, but Daming refused Lin Mo's plea.

Lin Mo knew that Daming was using Shama to commit murder, and in order to avoid becoming the next victim, he had to send out a distress signal. Initially, Lin Mo had hoped for his girlfriend Xiao Ai's help, but after more than a month had passed without a visit from her, he suspected that the sanatorium had tampered with something. Lin Mo observed everything around him, and the sound of a piano in the lobby caught his attention. He improvised a distress melody and sat down next to the young pianist, playing along with him.

After entering the Angel Sanatorium, Xiao Ai tried to visit Lin Mo during the designated visiting hours but was always denied by the nurses. This time, the reason for the refusal was that Lin Mo had suffered minor injuries, and Xiao Ai was worried about him. Frustrated by the sanatorium's insistence on not allowing her to see Lin Mo, Xiao Ai thought about scaring them by calling the police. However, Daming approached her and told her that if she wanted to call the police, she could go ahead, but she would be the one who disrupted the sanatorium's administrative order, and when the police arrived, she didn't know who would end up being dealt with.

Scared by Daming's words, Sasha turned around and walked back, feeling down. Suddenly, piano music resonated throughout the sanatorium.
