In the 1980s, as much of the world was being ravaged by horrific diseases like HIV/AIDS and tuberculosis, three young people barely out of their teens-Jim Yong Kim, Paul Farmer, Ophelia Dahl-came together in a squatter settlement in Haiti determined to provide medical assistance. They expanded beyond Haiti to Peru, then onwards to Rwanda, where they helped rebuild the country's health care system. This documentaray explores how, as a result, world policies changed, deeply entrenched ideas transformed, and millions of lives were pulled back from the brink of death.
