S2·E1 The Day His Medical License Returns

Black Jack is given a chance to redeem his medical license, but refuses and is arrested. During Black Jack's imprisonment, an Italian billionaire who was encountered in the other series begs Black Jack to save his grandson, knowing that Black Jack was the only doctor with the necessary talents. The head of the medical association in Japan refuses to release Black Jack despite the billionaires attempt at bribery, and the operation is taken on by Dr. White who attempts to do the operation using a robotic surgical aid. The billionaire visits Black Jack in jail and tells him of the boys miraculous recovery, but Black Jack states that the recovery was too dramatic, and the boy dies anyway. Enraged at the death of his grandson, the billionaire puts out a hit on the son of the head of the medical association. Black Jack is released from prison and ordered to save the boy.
