Doc is a small-town medic in the old west, an anachronistic pacifist, ecologist and integrationist with an Indian wife and mixed race son. His father Johnny, by contrast, was a famous gunslinger who now wants to retire from his life of violence. There are tensions though, as Doc still resents his father's lack of attention and worries over his influence on Doc's young son. But when old enemy Jack rides into town, Doc and his father must find a way to save the day without relying on the gun that Johnny has promised to give up.
