Regarded as one of the fastest gunmen in Texas, Colorado is ambushed and left for dead. Wounded, he stumbles across an isolated ranch and is nursed back to health by its owner, Helen Blaine. But the ranch is under the protection of Quanah, a Comanche chief, who forces Colorado to fight the Comanche's best warrior, to prove his worth. When challenged by another noted gunslinger, Colorado outdraws and kills him. The best option is to flee, but he and Helen arrive at Adobe Wells just in time for it to be attacked by Indians. After a battle with the Indians, Colorado's reputation still stands, until a new challenger, Jake Cobb, arrives, determined to prove that he is the man to topple the fastest gun in Texas.
