Watch My Lai (2010) : Full Movie Online Free What drove a company of American soldiers – ordinary young men from around the country – to commit the worst atrocity in American military history? Were they “just following orders” as some later declared? Or, did they break under the pressure of a vicious war in which the line between enemy soldier and civilian had been intentionally blurred? American Experience focuses on the 1968 My Lai massacre, its subsequent cover-up, and the heroic efforts of the soldiers who broke ranks to try to halt the atrocities, and then bring them to light.
