It was January 1968, a year that would be saturated in violence and historical change. But in a gray prison cafeteria, impervious to the tumult outside, hard men doing hard time witnessed the making of a legendary album that would catapult a country singer to international stardom. Johnny Cash at Folsom Prison remains one of the greatest live albums ever made, and the man himself one of America's greatest troubadours and advocates for prison reform. As the sound of the crowd's applause begins to rise over the scene, the present melds with the past and the ghost of that famous day in 1968, when a man in black strutted out onto a makeshift cafeteria stage and declared, "Hello, I'm Johnny Cash," re-appears. "Johnny Cash at Folsom Prison" examines the single most important day in the career of the legendary Man in Black and the prison where it took place.
