Six characters recreate different stages in Bob Dylan's career. Begins with the wanderings of an 11-year-old black runaway named Woody Guthrie. His raucous duet with Richie Havens on "Tombstone Blues." Ends with a silver-haired Billy the Kid watching the Old West die before his eyes. In the interim, there's the folk singer-turned-preacher, the actor, and a rock star.
