A family of musicians who live in the mountains descend on Mayberry to await the arrival of their daughter Charlene's fiancee. When Andy tries to help by putting them up in the courthouse, he gets more than he bargained for when Charlene suddenly sets her sights on him.

The Darling clan is back and this time need Andy's help to wed their daughter Charlene to Dud Walsh before crazy old Ernest T. Bass makes good on his threats to kidnap her and take her for his own. Andy sets Barney up as a decoy bride while the real wedding takes place elsewhere. The plan works, until Ernest kidnaps Barney and decides he's just as good a bride as Charlene.

While having dinner at the Taylor household, mountain man Briscoe Darling (Denver Pyle) mistakes Aunt Bee's usual hospitality for affection and whisks her away to his cabin to marry her, quite against her wishes. But when Aunt Bee takes it upon herself to "civilize" him, he wonders if hospitality is all it's cracked up to be.

Charlene Darling returns to Mayberry and announces that she has divorced her husband and now, according to folklore, must marry Andy. Desperate for a way out, Andy reads up on mountain folklore and finds a peculiar ritual that will void the marriage, if only he can get Barney to ride the horse.

The Darling family returns to Mayberry seeking a future husband for their 3-month-old daughter. To Andy's horror, they choose Opie, and he finds he will have to scare up a little witchcraft to get out of this one.

The Darling Family comes back, suddenly rich. They want their sons to marry well, and decide they should pick from the women of Mayberry.
