Slaughter (aptly played by veteran actor Sam Buffington) was a former Civil War hero who turned to cattle herding after the war was over.
Slaughter has a reputation as being being tough as nails and there really isn't any job too big to handle. He's almost a comic book Western hero in a way; he's not quite real like Paladin or Matt Dillon.
That doesn't hinder the series at all. It's just an exciting Western that's a bit different from the others of the same time period on radio and on TV.
The most-exceptional thing about the series though is the amazing sound quality that remains intact after all of these years. It's even better than you think it will be when I say the sound is "superb."
The show is so unappreciated that it sadly does not even have a Wikipedia entry.
