After Reese leaves two nuns near Massacre Mission, Joe and Chad must go there to remove the nuns. They find the threat from the Comanches to be non-existent but find outlaws are an issue plus they have to do manual labor for a change.
Reese is ordered to escort to nuns to an abandoned Catholic mission. They plan to convert the local Comanche Indians to Christianity. Reese, and later Chad and Joe, cannot convince the women of the danger, but little do the Rangers realize that their real peril will come from the outlaws that have hidden their ill-gotten loot under the mission chapel's floor.—David Bassler
