In resident Lin Hao's home, his wife is deeply distressed physically and mentally by the noise generated late at night by the upstairs neighbor. Lin Hao goes over to communicate and offers noise-canceling slippers, but is treated rudely by the other party. The property management acts as a peacemaker blindly, and neighbors are led astray to misunderstand Lin Hao. Lin Hao does not act impulsively or aggressively, but insists on thoroughly preserving various evidences of the noise and the other party making trouble. He picks up the weapon of the law, joins knowledgeable neighbors to file a lawsuit, and defends his rights relying on conclusive evidence and legal rules. In the end, the court makes a fair judgment, the infringing party bears corresponding compensation, and peace returns to the home, which also proves that forbearance cannot trade for respect, and complete evidence and the law are the powerful reliance for guarding one's own rights and interests.
