When Clancy Emmers is ejected from a retreat in Arizona, he meets Jefferson Prile, a black man just out of prison, his white girlfriend May and another ex-con, Stanford Talbot, and hitches a ride with them across the Southern states to his home town in Georgia. He is not to know that this is the beginning of a journey in which he must confront issues, emotions and prejudices that lie not only just beneath the surface of modern-day America, but also deep within himself. Nor is he aware of the existence of the Black Unicorns, a determined group of black revolutionaries, one of whom -- Jefferson Prile no less -- has been given a very special assignment.
