This is an early John Wayne western, made a couple of years before John Ford's "Stagecoach" made him a star, but he has a lot of star quaity here. (It's the same movie as "Born to the West" but they added a few minutes of footage of cattle and re-named it "Hell Town.") Wayne plays Dare Rudd, a drifting Montana cowhand and gambler who stays in a town in Wyoming to work for his cousin Tom because he has fallen for Tom's girl, Judy. Tom and Judy ride out to see Tom's herd of cattle where Dare is working. Dare immediately starts flirting with Judy who is still on her horse. Tom has dismounted. Then we see a shot of a western diamond-backed rattlesnake in a defensive pose and we hear a loud rattling sound. The sound spooks Judy's horse and it quickly rears up and starts to run and she can't stop it. Conveniently, none of the other horses are spooked, and Tom and Dare both jump on their horses and ride after Judy. It's Dare who rescues her, pulling her off her horse onto his. The scene is just an excuse for Dare to be a hero and to finally get his arm around Judy. It's an unusual rattlesnake scene because we don't see anyone shoot the snake or even worry about it after it scares the horse.
