The Last Bullet!

Tex Dawson, the Western Kid, is riding along the range with his horse Whirlwind and dog Lightning when someone begins to shoot at him. Taking cover, Tex and Lightning sneak around the ridge and ambush the shooter and subdue him. He learns that his attacker is an engineer and gold prospector named Buddy and his wife who mistook the Western Kid as one of Ridge Blackstone's men. They explain that Ridge has been following after them and forcing them to reveal the locations of his Buddy's gold finds and staking the claims for himself. Tex tells the couple that he'll help them deal with Ridge and his goons.

As the Western Kid and Lightning head back down the ridge he is confronted by Blackwell and his gang who have come to silence him and force the couple to reveal the location of their latest find. However, the Kid is faster at the draw and empties one of his guns to incapacitate six of Ridge's minions while bolting for cover. Having counted his shots and noting that he has six men left, Ridge leaves the scene telling his men to deal with the Western Kid. However while the Western Kid deals with the last of Blackwell's men, Blackwell himself is ambushed by Whirlwind, who knows the outlaw off his horse.

Knowing that the Western Kid has no bullets left, and he himself only having one remaining Ridge believes that he still has the upper hand against the cowboy hero. Tipped off by Lightning, Tex manages to trick Ridge into firing his gun in the wrong direction and then easily defeats Ridge in a fist fight, beating him up until Ridge agrees to surrender and give back the gold prospects that he stole from Buddy and his wife. With their stolen property returned to them, Buddy is about to sign over a share to the Western Kid in thanks, but he and his wife realize the hero has already departed without even so much as thanks for his help.

Mystery of Thunder Canyon!

The Western Kid goes to Thunder Canyon, the birthplace of his horse Whirlwind, to investigate reports that the horses in the region have been mysteriously disappearing. Upon their arrival, Tex has to remind his horse not to forget that he is civilized and reins him in. As he rides into the region, Tex recalls how he rescued Whirlwind after his father was murdered by another horse known only as the Wild One, who still walks the area.

That night as Tex camps out for the night, Whirlwind breaks free of his tether and goes after Wild One. Seeing this, Lightning rouses his master and leads Tex after Whirlwind. Meanwhile, Whirlwind has gained the upper hand against the Wild One and leads him on a chase through the canyon. Pursuing, Tex spots the Wild One fleeing the scene and although disbelieves that Whirlwind could have been killed, fears the worst. However, he comes across a man around the corner who denies seeing Whirlwind. However the Western Kid realizes the man is lying when Whirlwind begins to whinny behind a rock.

Before the Kid can act the man pulls his gun and explains that he had trailed the Wild One to lure horses into the area which he then captured and sold. Suddenly Lightning rushes off, giving the Kid distraction enough to fight off the man. The man then calls the Wild One, which tries to trample the hero, but Whirlwind breaks free and attacks his mortal foe. The man mounts Wild One and tires to flee the scene, but Lightning returns with a stampede of the other horses who chase their would-be captor and Wild One off a cliff to their deaths.
