A man with special dressing preferences, in order to find his sister who disappeared three years ago, deliberately changed into his favorite clothes in a secluded alley and led others to the mountains. After being mistakenly identified and sent to a farmer's home in a mountain village, he put away his edge, pretended to be submissive, secretly contacted his companions, and worked step by step in the crisis-ridden mountain village to collect local evidence of crimes against others. He used himself as bait to play against evil, and finally sought justice for his sister and all the victims, and used perseverance to complete the consolation for his family and self-salvation.
