A group of men obsessed with oil gather in a remote oil field region. Ichiro Kitazawa (Tatsuzaki) was one of them. He had a daughter-in-law named Harue Saijo (Takasugi), but he felt no affection for her. Ichiro, however, had spent the inheritance Harue had inherited from her father to find oil. Ichiro was now being bled by Butterfly (Hidaka), an eccentric female waitress at the Kinryu-tei. Harue took a train one day to visit Ichiro. She then befriended a man called Ken Matsuki (Dainikata), who had saved her from a crisis. Matsuki was a friend of Kitazawa, a man who was also passionate about the oil search.
