At the heart of Sister, Brenda Davis' documentary debut, are three inspiring stories of an Ethiopian health officer, a midwife in rural Cambodia, and a traditional birth attendant in Haiti. When Davis met Goitom Berhane in Ethiopia in 2008, she was taken with his vivacious personality and dedication to solving the maternal health crisis in his country. Goitom's example encouraged Davis to explore women's health as an international human rights issue. Eventually, he became a central figure in her film.
