20th Year Implication

Black Jack and Pinoko are staying at a resort hotel at the top of a mountain. A seriously ill patient is brought to the hotel, but when the hotel goes on strike, the commissioned doctor, Dr. Yabu, goes home on his way to treat the patient. When Mizuhara, a guest with an incurable disease, writes his will and opens a vial of pills, they hear the patient's son, Ricky, crying in the hallway, and they ask Black Jack to treat his father.
