Narisawa Minko (Ryoko Yonekura) is a beautiful hostess. She once dreamed that she could become an excellent jewelry designer. However, in reality, she was completely trapped by her paralyzed husband. In order to take care of her husband, Minko shouldered all the responsibilities of the family on her thin shoulders. However, her husband often got angry with her because of Minko's special profession. One day, a man named Kotaki (Kouichi Sato) found Minko and not only gave her many valuable jewelry, but also promised that if Minko could abandon everything she had, she could realize her dream. Minko was ruthless and burned down the house and killed her husband. After that, under Kotaki's arrangement, Minko became the mistress of the gangster boss Guitou (played by Hira Mikijiro), and began to climb to the top of the food chain.
