The rise of country music legend Johnny Cash (Joaquin Phoenix) begins with his days as a boy growing up on the family farm, where he struggles under the scorn of his father (Robert Patrick). As the years pass, Cash ends up in Memphis, Tenn., with his wife, Vivian (Ginnifer Goodwin), and breaks into the music scene after finding his trademark sound. While on tour, Cash meets the love of his life, singer June Carter (Reese Witherspoon), but Cash's volatile lifestyle threatens to keep them apart.
