Tezuka Osamu was a popular cartoonist who created such titles as "Astro Boy" and "Jungle Emperor," but by 1973 he is considered old-fashioned. He is in heavy debt and his company Mushi Production has gone into bankruptcy. Through all of this and with the help of friends as Kabemura Taizo, chief editor of weekly manga magazine Weekly Shounen Champion, he is able to create manga "Black Jack," which becomes another huge hit. His career is now revived.
