The whole hospital isolated Lin Yanqiu because she refused to cut in the queue for surgery for the powerful. On a rainy night, she completed 17 cases of organ harvesting alone, but saved 17 dying families. When Shen Zhiyao discovers the donor's last wishes hidden in her surgical records, the two begin to join forces in the cracks of the system. Zhou Song's silence, Chen Rui's awakening, Huo Ting's manipulation, Lao Zhong's diary - every hidden thread is tearing apart this silent hospital. No one knows who will be the eighteenth person to be rescued or the eighteenth donor to be sacrificed on the next rainy night.
