Singer Danny Scofield, née Fields (
Donny Osmond), thinks his hillbilly relatives (
Richard Paul,
Marion Ross,
Slim Pickens and
Loni Anderson) will ruin his chances of impressing record producer Steve Sorrell (
Rich Little), who becomes attracted to Danny's sister Kitty (
Loni Anderson), who doubts her commitment to her fiancé (
Randall Carver). An author (
Eve Arden) pictures the Scofield family as potential characters for her next book and poses as a mountain woman to get the grandfather (
Slim Pickens) to open up to her. Doc, Isaac, and Gopher's (
Bernie Kopell,
Ted Lange and
Fred Grandy) cabins become flooded, so they bunk in with Capt. Stubing (
Gavin McLeod) temporarily, keeping him awake at night, and annoying him incessantly. Two couples (
Denise Nicholas and
Robert Guillaume, and
Pam Grier and
Richard Roundtree) take the cruise together and one of the couples' wife (
Denise Nicholas) tries to convince the other couple's husband (
Richard Roundtree) that their spouses are having an affair.
