Sister follows maternal health workers in Ethiopia, Cambodia and Haiti though beautiful and brutal circumstances. A surgical health officer in Ethiopia, a rural midwife in Cambodia, and a traditional birth attendant in Haiti work tirelessly to save the lives of women and babies. If there is a war on women, these health workers are the shock troops in their defense. Their stories reveal strategies in place to improve maternal health and the crisis of maternal and newborn mortality, shedding light on when the strategies work, when they don't work and how the lack of transport, communication and education create weak links along the way. Sister is a film directed, produced, shot and edited by women.
