Episode 2 recap: The crowd searched for the control room.

Chun Yu and Lao Lin were surrounded together, and only when Gao Xuan (played by Wei Zhe Ming) attracted a monster did Chun Yu and the others manage to escape to an intersection. Gao Xuan led them to the second floor. She had been here for several days in advance, so she was naturally more familiar with the place than they were. Suddenly, Chun Yu had a thought that the mysterious figure she had noticed when she first entered the building was Gao Xuan. Gao Xuan mentioned that this place might be a parallel world in reality, or there was a possibility that someone had implanted other thoughts in them.

Chun Yu and the others all arrived here after a car accident, but Gao Xuan claimed that she had unintentionally ended up here while sleeping in her dormitory. Obviously, this reason was met with suspicion by others, and they didn't believe her at all. Lao Lin discovered an empty box containing six bags, each labeled with the number 19, coinciding with the number of people present.

Each of them opened a bag, which contained an axe, a flashlight, a pot, a map, matches, and a portable fan. Gao Xuan suggested that the things in their hands must be useful, and Zhang Tian Qiang became interested in the map Chun Yu had. Chun Yu proposed exchanging items.

At that moment, Gao Xuan walked towards the back door with a flashlight, and Zhang Tian Qiang swapped the map for matches. In fact, during Chun Yu's escape, she fiercely resisted the monster and discovered that the monster was afraid of light, disappearing instantly. Zhang Tian Qiang left with the map and A Yong, while Chun Yu had already memorized the map in her mind before happily exchanging it with Zhang Tian Qiang.

Chun Yu drew the entire map on the ground and analyzed it with Gao Xuan. They decided to first find the control room. Zhang Tian Qiang and A Yong once again tried to use the axe to break the window but realized it was ineffective. While they were studying the map unwillingly, the monster appeared before them.

Chun Yu held a candle and searched for the power distribution room, where she discovered that the shadow puppet on the wall transformed into a human form and would return to the painting whenever it saw light. Qing You and Lao Lin hid in the storage room and heard movements at the door, mistaking it for Chun Yu's arrival. However, the monster began pounding on the iron door, and luckily Gao Xuan arrived with a flashlight, causing the shadow puppet monster to disappear instantly.

Zhang Tian Qiang and A Yong were chased to Gao Xuan's side, and when the shadow puppet encountered the flashlight, it instantly fell down. Zhang Tian Qiang and A Yong realized that the shadow puppet was afraid of the flashlight and prepared to seize the opportunity to grab it. Zhang Tian Qiang held Qing You hostage and used her as a trade for the flashlight.

Gao Xuan didn't completely trust Zhang Tian Qiang, so Lao Lin acted as an intermediary, handing the flashlight to Zhang Tian Qiang and pulling Qing You back. Zhang Tian Qiang, in order to keep the flashlight, abandoned A Yong and ran away alone.

Gao Xuan led Lao Lin to continue moving forward, while A Yong remained alone in place, feeling sad. At that moment, Zhang Tian Qiang pretended to be a ghost and frightened A Yong. When A Yong realized he hadn't been abandoned, he felt happy. Gao Xuan and Lao Lin arrived at a corridor and heard movement inside. Gao Xuan lit a match, and Chun Yu appeared from around the corner. Their eyes met.

The number of shadow puppets increased, and Chun Yu suggested going to a control room. Zhang Tian Qiang and the others got lost in the corridors and unexpectedly stumbled upon the power distribution room. They opened the door and walked inside, but the flashlight started flickering and ran out of battery. Meanwhile, Gao Xuan also found the power distribution room. They pulled up all the switches, but nothing happened.

At that moment, the shadow puppets found them. They used various tools to block the entrance, but the power of the candles was limited. The candles were burning out quickly, and they suspected that the switch might be in another power distribution room. Zhang Tian Qiang's flashlight was also running out of battery. With hope in his heart, he opened a switch but found that the lights didn't turn on while the fan started spinning. At that critical moment, the flashlight went out.

Chun Yu's candle burned out, and the shadow puppets entered in groups. Chun Yu was racing against time to replace a fuse, while Gao Xuan and the others tried their best to stop the shadow puppets. Seeing everyone getting injured, she managed to connect the power in the last second. The entire building's lights turned on instantly, and the shadow puppets disappeared, turning into a piece of paper.

Zhang Tian Qiang and A Yong embraced, thinking they were going to die there, but when they opened their eyes, they saw bright light all around. On the other side, Chun Yu was lying in a hospital bed. She slowly opened her eyes and realized she was in a hospital.
