Kyoko, the heroine, receives a surprise visit from her ex-boyfriend Shunichi after a lapse of four years. Shunichi has decided to commit suicide and asks Kyoto to die with him. Kyoto agrees because she has been suffering from the conflict between her inner search for freedom and her inescapable role as her politician father's second secretary. Kyoko and Shunichi make their way to Kyoko's deceased grandfather's land which is hidden deep in the mountains. In grand Mother Nature, however, they start thinking not just about dying, but about doing something to heighten the value of their lives in their final weeks. They plan to create a tomb so that the ultimate aim of their lives is death. However, when they hear that Kyoko's parents have been killed in a sudden accident, the strange harmony of their lives is disrupted. They decide to go down the mountain to bury her parent's remains. As Kyoko returns to society, she re-evaluates the discontent she felt in her former life and draws the conclusion that she must pursue the hidden potential within herself which transcends the limits of an individual, by using her body rather than striving to kill herself. In order to pursue their new goal they choose to do something very simple and unproductive, such as piling up concrete again and again. Their endless act continues, and in the slow stream of time, their spirits and bodies metamorphose so that they develop new wisdom of which they have never before been aware.
