In an old community in a modern city, Lin Chuan, a young man with both legs amputated who lives alone, was falsely accused of being a midnight noise maker. He was ostracized by his neighbors and targeted by the property management. In fact, it was Li Mingxuan, a returned elite upstairs, who framed him to cover up the truth. Lin Chuan relied on his extraordinary auditory acuity, and with the help of Chen Siyuan and psychological counselor Xia Luo, he peeled off layers of cocoons, restored the sound evidence, tore through Li Mingxuan's hypocritical mask, and finally brought this highly intelligent criminal to justice, cleared his grievances, and gave himself a new life.
