ENTAL is a feature-length documentary that observes the complex world of an outpatient mental health clinic in Japan, interwoven with patients, doctors, staff, volunteers, and home-helpers, in cinema- verite style. The film breaks a major taboo against discussing mental illness prevalent in Japanese society, and captures the candid lives of people coping with suicidal tendencies, poverty, a sense of shame, apprehension, and fear of society.
