You may not have heard of Nasrin Sotoudeh, but she has had quite an impact. As one of the most courageous and outspoken human rights advocates in Iran, she has fought to defend those without a voice against a harsh authoritarian regime, at great personal cost. Her story is now the subject of the new documentary "Nasrin," and that film provides the focus of the next episode of The Good Media Network's Mission Unstoppable podcast. Join host Frankie Picasso and yours truly tomorrow, March 18, at 1 pm ET, for an interview with director Jeff Kaufman and producer Marcia Ross about their film and the courageous attorney's work.
