Hotel clerk Dobie (Clark) seems like an inoffensive little guy. But when hulking mountain man Big Dan (Whitney) brings in his Indian wife Rose (Dickinson), Dobie turns racist mean. He's got some reason since her tribe has killed many whites. But what's Matt to do when Rose disappears after Dobie has riled up the town.
Good byplay with Doc and Chester— they make it seem so effortless and natural. It's a strong story to just before the end. At that point there's a turn-around that seems pretty contrived to me, and worse, weakens the overall impact, at least in my little book. Also, note how the script talks around the fact that Rose has been gang raped without stating it. That powerful terminology was too strong for standards of the 50's, so writers had to imply without stating. Nonetheless, it remains a compelling plot device.
(In passing—Peter Whitney's hulking frame made him a natural foil {6 episode appearances} for the equally towering Arness. Here Whitney plays basically a friendly guy. However, catch him as the downright scary Ira, 250 lbs. of righteous anger in the episode Kangaroo {1959}.)
