The story of Meron Estefanos, a journalist who in 2011 got a troubling tip: A group of Eritrean hostages were being tortured and held for ransom in the Sinai desert. Along with the tip was a phone number. Meron dialed it, and soon dozens of desperate hostages were begging her for help. Their pleas were impossible for Meron to ignore: Soon she was talking to the hostages regularly and devoting her life to trying to save them.
