When tragedy strikes, Kane embarks on a journey of faith which prompts the Ronin to seek out his true master in the spirit world... both will face many battles along their interweaving roads to peace.

In a general hospital near bankruptcy, the reduced staff is working under a severe stress. During the emergency attendance to a burned patient with Dr. Uozumi (Masanobu Takashima) and two other nurses, Dr. Akiba (Kôichi Satô) and the nurse commit an error, injecting sodium chlorate and killing him. Dr. Uozumi convinces the team to forge the report to save their careers. Meanwhile, an ambulance leaves a patient in the emergency with a lethal infection. When the muscles and internal organs of the patient liquefy, Dr. Kiyoshi Akai (Shirô Sano) convinces his two colleagues to examine and research the virus, leading the employees of the night shift to a tragic end.
