China's organ transplant industry has grown into one of the busiest in the world, and this film asks where the organs actually come from. Investigators and former officials lay out evidence that prisoners of conscience, many of them Falun Gong practitioners, have been killed to supply livers, kidneys, and hearts on demand, with wait times for a matching organ sometimes measured in days rather than years. The film traces the government's shifting explanations, from denial to claims that organs came from executed criminals who consented, and sets those claims against transplant statistics that researchers say do not add up. Interviews with human rights investigators and testimony from witnesses outside China build the case that this is a state-run system rather than isolated wrongdoing. Hospital advertisements and transplant tourism are shown as evidence the trade is commercial as well as political. It is a grim, tightly argued twenty-two minutes built around a simple question: who are these organs actually taken from?
