When a former Princeton music professor stumbles into choir practise at a small-town church, he finds singers that are out of tune in more ways than one; despite their differences, he and his new cohorts may just help each other reinvent.

Arthur defies local customs, and the choir pays for his rudeness; for Cash's sake, Ginny vows to say nothing bad about Wayne.

Arthur helps Ginny conquer stage fright; Reverend Jax is caught in the rift between Wayne and Dwayne.

When Arthur is faced with a choir rebellion, he decides -- against Ginny's advice -- to take on Adams, the group's alpha, at their annual deer hunting trip; Wayne takes Cash on his first hunting trip to teach him how to be a man.

Arthur deals with Jean's father, who attempts to take their family houseboat back; Reverend Jax hosts a singles night, where Ginny and Dwayne finally address the elephant in their relationship.

When Ginny tries to step into a new management role at work, Arthur helps her overcome her fears of inadequacy; when Dwayne opts out of a long-standing Halloween tradition, Wayne fears that they are growing apart.
