On their way back from the Cannes Film Festival in 1971, filmmakers Wakamatsu Koji and Adachi Masao visited Lebanon to meet Japan's Red Army faction and the Popular Front for the Liberation of Palestine to shoot a newsreel film promoting the Palestinian resistance.

Tatsuya Kawakami's mother becomes a member of a religious group after her husband commits suicide, and makes a large donation to the organization. Her three children are forced to live in poverty, and her eldest son, who is blind in one eye due to illness, takes his own life. Kawakami comes to believe that the religious group has ruined his life, so he creates a homemade gun and carries out an assassination plot against former prime minister Shinzo Abe, who has close ties to the religious group, which has been accused of siphoning off money from its members.
