Michi's first encounter with Nobuyuki Ishida, secretary to the chairman of a private school, takes place in the drawing room, when she attempts to swindle him out of two million yen for alleged rape by his son. Akie, Ishida's wife and the chairman's daughter, offers her a million, but he gives her what she demands. Now Michi is not only satisfied, but she has a mad desire for Ishida and calls him every day asking for a date. His sympathy for her gradually evolves into love, and he soon allows her insatiable passion to strip him of his decency.
