Apart from Rod Cameron starring as a villain (he almost always played heroes), there isn't a lot to make this a must-see western. It's based on bad history like so many other B-westerns.
Belle Starr was a real life villain, though her exploits were greatly exaggerated to sell pulp magazines in the old days. She also was murdered when she was 41. In this film, she's killed as well...but in a way VERY different from real life. But as I said these old westerns often get the facts wrong. In the case of the film, she's murdered by one of her own gang members, 'Bitter Creek' Yauntis. But he lies...telling Starr's daughter that the Deputy Marshall (George Montgomery) shot her...though if he did, it was because she was an outlaw! Despite this, Cimarron (Belle's daughter, played by Ruth Roman) joins Bitter Creek and his gang...and sees them commit all sorts of atrocities...yet she believes he's a nice guy. Apparently, Cimarron is rather dim and it takes her a while to see the light. As for the Deputy Marshall, he's a stereotypical good guy out to clean up the west and avenge a few wrongs.
Overall, a pretty average western with little to make he recommend it, though little (apart from rewriting history) to hate either.
If you do watch, pay attention during the bar fight. The stuntmen are VERY obvious during this scene.
