Watch Messenger on a White Horse

Argentina's 1976-83 dictatorship was one of Latin America's most gruesome. Under the guise of a war on communism, the ruling Armed Forces tortured and "disappeared" thousands of young left-wing students, activists and militants, leaving a trail of devastation that would haunt the country for decades. But a soft-spoken journalist named Robert Cox had the courage to speak out.
