HIV-positive men and women in Zambia sit for interviews about what antiretroviral treatment did to their bodies within weeks of starting it: people who could not stand up out of bed are shown walking, working, and caring for their children again. The film, directed by Lance Bangs and executive produced by Spike Jonze for (RED) and HBO, treats the drugs themselves as the subject, two pills a day costing about 40 cents, and lingers on how little separates that cost from the difference between dying and recovering. Doctors and aid workers explain how a diagnosis that once read as a death sentence in the region became survivable once the pills reached local clinics, and patients describe the specific symptoms that vanished, weight returning, energy returning, in as few as forty days. The film stays close to individual faces and voices rather than statistics, letting the visible before-and-after argue the case for funding treatment access. It closes on people back at ordinary life, working and raising families, as the plainest evidence the film offers.
