“Ladies First” explores the role of Rwandan women in building bridges between Hutus and Tutsis 10 years after the genocide that killed 800,000 people in 100 days. Director Gini Reticker and producer Deborah Shaffer were co-producers of the Oscar-nominated 2003 documentary “Asylum,” about a woman who flees Ghana to avoid genital mutilation and runs into trouble with U.S. immigration.
