A musician is discovered in a Detroit bar in the late 60s by two celebrated producers struck by his soulful melodies and prophetic lyrics. They record an album which they believe is going to secure his reputation as the greatest recording artist of his generation. In fact, the album bombs and the singer disappears into obscurity amid rumors of a gruesome on-stage suicide. But a bootleg recording finds its way into apartheid South Africa and, over the next two decades, it becomes a phenomenon. Two South African fans then set out to find out what really happened to their hero. Their investigation leads them to a story more extraordinary than any of the existing myths about the artist known as Sixto Rodriguez. This is a film about hope, inspiration and the power of music.
