Documentary “Bad Blood,” by director Marilyn Ness. This movie debuted July 28 in New York City.

What if your life-saving medicine contained deadly viruses and the drug manufacturers, the government, and your own doctors knew but failed to warn you? Through the eyes of survivors and family members, BAD BLOOD: A Cautionary Tale chronicles how a miracle treatment for hemophilia became an agent of death for 10,000 Americans. Faced with evidence that pharmaceutical companies and government regulators knew the product was contaminated with HIV and hepatitis, they launched a powerful and inspiring fight to right the system that failed them and to make it safer for all.
