Reese is sent out to escort the Bordeaux sisters and gets his face slapped before finding out the sisters he's looking for are nuns. He escorts them to a settlement and makes them promise not to continue to Massacre Mission where priests were slaughtered some years earlier by hostile Comanches who are still on the warpath. The sisters telegraph Parmalee they have left for the mission anyway and the Captain sends Chad and Joe to protect them. They arrive to find the sisters smoking a peace pipe with the Comanches, who claim they have had nothing to do with the raids. Things are soon complicated by the arrival of outlaws who have treasure buried in the mission's sanctuary. They have been dressing like Comanches and committing the raids while using the mission as their hideout. Chad and Joe capture the gang with the help of the Comanches and each donates his share of the reward money to the mission.
