"The arc of the moral universe is long, but it bends toward justice." Nearly fifty years ago, Martin Luther King Jr. proclaimed these words as he called for racial equality after completing the historic voting rights march from Selma to Montgomery in Alabama. But the question still remains today: has the United States of America made true progress in becoming a society in which all people are treated as equals? Reflecting on our nation's ongoing pursuit of equal rights, Investigation Discovery presents ID FILMS: MARCH TO JUSTICE produced exclusively for ID by NBC News' Peacock Productions. With unprecedented access to a civil rights pilgrimage attended by champions of the movement and three generations of the Kennedy family, MARCH TO JUSTICE premieres exclusively on Investigation Discovery on Monday, February 25 at 8 PM (E/P).
