What is the plot of "The Bride Comes to Yellow Sky"?

Jack Potter, the town marshal of Yellow Sky, is returning
home with a surprise for the rest of the townspeople: He has gotten married and is being
accompanied by his new bride. They are a bit overwhelmed by the train's opulence, to
which neither of them are accustomed. Meanwhile, in Yellow Sky, the men drinking at the
Weary Gentlemen Saloon get the word that Scratchy Wilson is near. The bartender
immediately closes the bar, for Wilson is known to be quick with a gun when drunk. When
Wilson cannot get inside, he decides to head to Potter's home, because Potter is the
only man who will face him when he is in this dangerous mood. When Potter and his new
bride arrive, Wilson faces off with Potter. Potter tells Scratchy that he has no gun,
and Wilson demands that the marshal draw down. Finally, Potter tells Scratchy that the
reason he has no gun is because he has just gotten married. When Wilson sees the new
bride, he walks away, declaring in disgust,

"I
s'pose it's all off now."
