“The arc of the moral universe … bends toward justice” said Martin Luther King Jr., but people can speed up the bend. In the 1980’s, doctors Paul Farmer and Jim Yong Kim plunged with youthful exuberance into the herculean task of improving health care in Haiti. The key to success? Listening to the needs of the people and training local communities to help themselves. With the help of activist Ophelia Dahl and others, they created Partners in Health, expanding their model to ten countries, savings thousands of lives, and insisting on equity in the distribution of medicine, all while maintaining the good humour and optimism that shine in this film.
