Query: Gripping and Intensive

Yes, it is a documentary and, yes, it is a monologue. Yes, he discusses the sex trade in Cambodia which is extemely explicit. But this is about Cambodia. This is about the Killing Fields. This is about our involvement in that history. There is nothing gratuitous. Gray is captivating as he sits on a darkened stage with his words and topics accented with strategic lighting, maps, sounds and video clips. You will leave this film with a new understanding of what happened from Cambodia to Kent State. He also has a unique insight into mankind. In this, his "Talking Cure", you will be compelled to try to answer the question that he wrestles with - 'Is morality a moving feast?'. This is an important film.
