 North Fork s new preacher and his wife are murdered by a gang of outlaws. Two of them pose as the new reverend and wife in order to help the gang gain unsuspected entrance to the town. The preacher uses his first meeting as an occasion to set up a distraction for the others while they rob the bank. Meanwhile, Mark has learned of the ruse, and is taken captive to keep him silent. Lucas and Micah must find Mark and stop the outlaws if they are not to carry out their designs against the bank.
