Roughly chronological, from 3/96 to 11/96, with a coda in spring of 1997: inside compounds of Aum Shinrikyo, a Buddhist sect led by Shoko Asahara. (Members confessed to a murderous sarin attack in the Tokyo subway in 1995.) We see what they eat, where they sleep, and how they respond to media scrutiny, on-going trials, the shrinking of their fortunes, and the criticism of society. Central focus is placed on Hiroshi Araki, a young man who finds himself elevated to chief spokesman for Aum after its leaders are arrested. Araki faces extreme hostility from the Japanese public, who find it hard to believe that most followers of the cult had no idea of the attacks and even harder to understand why these followers remain devoted to the religion, if not the violence.

A2 is a continuation of director Tatsuya Mori's film A (1998), an incredible view inside the compound of Japan's Aum Shinrikyo cult after its leaders carried out the deadly sarin gas attacks on the Tokyo subway in 1995. Most followers had no idea that the attacks were being planned, or even that their new religion had violent aspirations. After the attacks, these followers were left to rebuild the religion where they had once found peace in the face of overwhelming, and understandable, condemnation from the rest of Japan. Central focus is placed on Hiroshi Araki, a young man who finds himself elevated to chief spokesman for Aum after its leaders are arrested. Araki faces extreme hostility from the Japanese public, who find it hard to believe that most followers of the cult had no idea of the attacks and even harder to understand why these followers remain devoted to the religion, if not the violence.

Atsushi Sakahara, a victim of the 1995 sarin gas attack in Tokyo's subway system, travels with Hiroshi Araki, an executive of Aleph (formerly Aum Shinrikyo), the attack's perpetrators, visiting their respective hometowns and the university they both attended. Conversations unfold, building intimacy: we learn why Araki joined the infamous organization led by Shoko Asahara and why, still, Araki remains an executive member of the cult, even though he was not directly involved in any of the crimes.The beginning of a friendship, a trip for redemption, or the confirmation that each human has to go their own way.
