The two hour documentary is a celebration of the larger-than-life Johnny Cash from the unique perspective of the Man in Black's greatest songs, with the film being built around the 10 greatest Johnny Cash tracks, the "essentials". Each song brings to life a chapter in the story of America from the 1950s to modern day, as we tour the life of music and artistic expression of one of music's most storied talents. Through his music, Cash was ahead of his time in fighting against war, injustice, racism and prejudice.
