A skilled country doctor's talents are such that he can even perform operations as difficult and novel as removing a patient's kidney for the first time in Japan. Unfortunately for him, however, his wife's addiction to gambling is of such a magnitude that he is down to selling his underwear to make money. The image sticks and he becomes known as the 'underwear doctor.' On the other hand, his successful surgery's patient is so grateful he himself wants to become a physician.
