This is a routine western script that has been played out many times in this series plus is usually a main plot in about every western show or book since the beginning of the written word. What the writer has to do is change the setting and characters to produce and interesting plot and it seems the job was done well enough to at least stir some interest.
The main plot is when one of the gang members has been arrested by the law and the rest of the gang think of a way to spring their friend from the grasp of imprisonment. In this script, Matt is on a stage when Cody Tyce, the younger and wilder brother of the gang leader Yancy Tyce, gets caught by the Marshal when he tries to rob the stage. When word gets to Yancy, he vows to rescue his brother and make the Marshal pay for shooting another member that was in on the robbery.
With Festus out of town, Newly gets a telegram advising to meet the Marshal at an outpost outside of Dodge. When Newly gets to the stopping place the gang of robbers are already there where they will hold Newly as hostage until the stage carrying the captured gang member arrives.
Even though the story was well done by the actors involved, the circumstance of the situation did not lead itself to a suspenseful show. It was fairly obvious how the ending was to be played out early in the episode. And when one of the main characters gets shot, the writer came up with a unbelievable happening to keep the person alive. Not really a poor show but one that was predictable nearly from the start.
