On September 26th, 1983, an alarm sounded to indicate that five American nuclear missiles had been launched against the Soviet Union. Russian Lt. Colonel Stanislav Petrov defied military protocol, ignoring the incoming attack, confirmed by all the warning systems. He followed his own sense of responsibility and declared it a false alarm. His decision spared the world a nuclear holocaust. Decades later, this forgotten hero travels to the United States to accept an award from the United Nations and finally receive acknowledgement for his historical act.
