A bus carrying psychiatric patients got into a car accident on the highway. 24 patients took advantage of the chaos and escaped, hiding in a locally chaotic urban village. A few days later, all the patients were captured back. But were those captured patients real patients? I went to investigate in the identity of a private detective and found that the patients in the ward were all tied with ropes. Seeing my appearance, they were very excited, but unable to speak because their tongues were gone.
