It has been called the worst treatment disaster in the history of the NHS. More than 2,000 people died and thousands more were infected with HIV and Hepatitis C after being treated with contaminated blood products. All the victims were infected over 25 years ago, but even now new cases are still being diagnosed. Survivors and their families are trying once more to persuade the government to hold a UK public inquiry.
Panorama examines recently released documents, and asks if the government could have done more to save lives. The film hears the heartbreaking testimony of some of the victims and their families and explores the dilemmas of doctors who had to carry on treating their patients through the unfolding crisis.
