In the 1970s, as El Salvador was irrevocably approaching civil war, one man was known as the voice of the poor, the marginalized, the disappeared. Appointed Archbishop in 1977, Monsignor Oscar Romero worked tirelessly for peace, justice and human rights, in constant personal danger. Using the power of the pulpit to denounce official corruption, he inspired millions with his nationally broadcast sermons, until in March 1980, he was gunned down at the altar. With rare recordings and footage, and a wide range of interviews with those whose lives were transformed by Romero, including church activists, human rights lawyers, former guerrillas, and politicians, Monsignor is a timely portrait of the man's quest to speak the truth. true even if it cost him his life.
