A documentary that examines the issue of forced live organ harvesting from Chinese prisoners of conscience, and the response - or lack of it - around the world. It's happened before: governments killing their own citizens for their political or spiritual beliefs. But it’s never happened like this. It’s happened so often that the world doesn’t always pay attention.
