The story of two sisters in post-war Japan. One is a geisha and the other works for the tourist board.

When a group of young geologists declares a mountainside marked for residential development unstable, they are met with scorn on two fronts. On one end, they must contend with the local villagers who balk at the prospect of relocation; on the other, they face the ambitions of the headstrong lumber baron, whose actions will only further destabilize the land. Their pleas for reason ignored, the scientists can do little but observe as nature runs its inevitable course.
