Keiho (1999)

Masaki Shibata Sinichi is a theater actor who murders a man and his wife. Masaki confesses the crime and alleges that the reason for it was that the woman, five months pregnant, had criticized her show. It could be a very simple case to settle if it were not for the "mitigating liability" contemplated in the criminal system of Japan. Masaki must undergo a psychological test to determine his sanity.
