Journalist Takashi Hayami meets Ai Katsuragi, a member of a religious organization, Tenmu Jinshinko, which meets secretly at the tomb of the Emperor Nintoku. The group adheres to the nomadic way of life of its ancestors, which lacked family registers and fixed abodes, and flouts civic duties such as paying taxes, serving in the armed forces and compulsory education. Even when the government tries to crack down on a segment of the populace, they continue to discipline themselves in the way of living as ambulatory people. They rely on the company Ikarino to fund the various political, social and cultural activities they promote that protect their unique lifestyle. But when Ikarino becomes a giant conglomerate that destroys the forests and mountains that form the foundation of the Tenmu Jinkshinko, Hayami must join the group's struggle to save their way of life.
