1879. After decades of violence of fleeing, having gone everywhere from Florida to Mexico, a war-weary band of Seminole Blacks led by their sheriff, Desi Leans, and his wise-cracking deputy, Gay Day, have finally settled in the Oklahoma Territory. They have built their dream, Refuge, and they will do whatever it takes to make it work.
But they fear that it may all go up in smoke when an outlaw band of renegade buffalo soldiers, The Testimony Gang, comes to town. Desi strikes an uneasy truce with the gang until their true leader, the firebrand preacher, Prester John, arrives, promising to rain fire and brimstone down on all those who don't believe in his ways.
Will Refuge hold true to its promise or will it all be burned to the ground?
