本片根据首藤瓜於的同名原作改编。
A series of bombings occur and police track a lead, where they find the male protagonist Ichiro Suzuki and believe he is somehow involved. After psychiatric evaluation and rigorous questioning, the man is found to be emotionally vacant, highly intelligent with a savant-like photographic memory, physically strong and unable to feel any pain. The female lead who plays psychiatrist Mariko Mashiya is intrigued and attempts to discover what and how he came to this state, fueled by her own past personal tragedy and determination to seek the truth. Is he the psychopath they are all looking for?
自以为是的「善」比无可救药的「恶」更可怕。It's always easier to believe what you want to believe。火车道德观。充满讽刺意味的结局。我純潔的一刻勝過你一生的謊言。。生而为人。中二病也要拍电影。。全部都被導演騙了——世界上有些人的靈魂是怎麼也無法救贖的。迷失罪與罰。你我皆凡人。
