Black Jack is given a chance to redeem his medical license, by treating the son of Detective Takasugi who has Paget's Disease. The operation is a success, but Jack refuses to comply with the bureaucratic registration process and is arrested for practicing without a licence. During Black Jack's imprisonment, a former patient, the Italian billionaire Mr. Boccherini, begs Black Jack to save his grandson, but the head of the Japan Medical Association refuses to release Black Jack despite the billionaire's attempts at bribery. The operation is assigned to Dr. White who carries it out using robotic surgical aids. Boccherini tells Jack of the boy’s miraculous recovery, but Black Jack suspects that the dramatic recovery is too radical and the boy later dies. Enraged at the death of his grandson, the billionaire arranges for the son of the head of the medical association to be shot. The father pleads with Jack to save the boy and he agrees, but for an outrageous sum of money. (Source: Wikipedia)
