Richard Gere narrates this thoughtful chronicle of efforts to develop a vaccine for HIV/AIDS. Included: comments from Jon Cohen, whose book "Shots in the Dark" inspired the program; National Institute of Allergy and Infections Diseases director Anthony Fauci; ex-CDC official Don Francis, who is pursuing a vaccine; and Dr. Omu Anzala (University of Nairobi), who has studied HIV/AIDS-free prostitutes in Majengo.
