Enjoyed this film. It portrayed a post-Civil War mid-west (so it appeared)community in a way that could make you nostalgic. Not that everything was perfect: the Ku Klux Klan harassing a freed black man (the distinguished Puerto Rican actor Juano Hernandez)primarily because they want his land. That preacher Joel McCrae manages to talk them out of it by appealing to their basic decency works without being cloying. Initially a muscular Christian, he here uses his brain to do the Lord's work. Also believable was the community's vulnerability to disease. They had no laboratory-testing facilities to see if that well-water was the source. McCrae's self doubt in the face of all this is believable.As for the cast, I'm pretty sure I spotted an uncredited Peter Graves as one of Alan Hale's offspring.
