Kitagawa is an engineer charged with construction of a gigantic tunnel through the Japan Alps for the transportation of equipment in the building of the massive Kurobe Dam. The tunnel crosses an earthquake fault and Kitagawa is beleaguered not only by cave-ins and flooding, but by strife between management and the workers's union. Adding to Kitagawa's stress is the knowledge that as his attention is pulled inexorably toward the tunnel construction, his youngest daughter is dying from leukemia.
