A tall youngster searches for a job, riding across the infamous desert known as Satan's Lair, toward the isolated town of Apache Pass. As he reaches the midway point of the perilous ocean of sand, rifle bullets start to rain down on him. Cy Harper spurred and tries to outride the deadly rifle fire. For hours the dozen unknown riders chase his high-shouldered black stallion and keep firing. What Harper doesn't know is that his thoroughbred horse looks just like a mount ridden by a deadly hired gunman known as 'Lightning' Luke Cooper. Mistaking Cy Harper for the lethal 'Lightning' Luke, Judge Brewster and his men keep chasing and firing at Harper - they want the bounty that rests on Cooper's head. One of their bullets catches Harper in his muscular shoulder. He slumps, draped over the neck of his trusty mount as death keeps firing at him. Is this the end for an innocent drifter?
