Four people make an annual pilgrimage to a spot in the mountains where a cult group lived. Three years previously, the cult had put a genetically engineered virus in the water supply. The idea apparently was to kill off everyone in Japan and then repopulate it with cult members. The virus killed a few people and poisoned thousands, but instead of living and taking over, most of the cult members died.
