Aging, cynical Shunsuke is one of postwar Japan's most respected authors. While vacationing at an exclusive Japanese resort, he meets Yuichi, a stunningly gorgeous young man of limited means and intellect who is engaged to a prim, conventional young woman from a very well-to-do family. While he needs the marriage for financial reasons, Yuichi innocently confides to the older man that he feels no real physical desire for his bride, or for any woman. The crafty Shunsuke senses an opportunity to mold the malleable, gullible young man into an exquisite weapon of revenge against the female sex as a whole. He tells Yuichi that his inability to feel desire for women is not a weakness but potentially a tremendous source of strength. He advises the young man to go through with the marriage and gain financial security, but also to omit no opportunity to experiment with the emotions of others, and to have as many affairs as possible with both women and men.
