When renegade Pawnee Indians attack some local ranchers, Matt and Major Evans think that white gunrunners supplied the Renegades the rifles. Matt, Chester and Indian scout Tobeel, go the scene of the massacre to pick up the trail of the renegades in the hopes that the Indians will lead them to the camp of the gunrunners. One thing that the gunrunners were not counting on was that the riffles that were sold to the renegades were an outdated Henry 44. Matt thinks that once the Indian renegades find out that they have been cheated and have purchased outdated rifles that no longer have the ammunition in supply, the Indians will go after the gunsmugglers. The Indians do take out revenge on one of the Gunsmugglers, but the other man tries to flee. With the information supplied by a cowboy on the prairie, Matt finally arrives in the camp of the remaining gumsmuggler to confront the man. (thetvdb.com)
