In July 1952, the Kettles help out cousin Rodney Kettle in Hawaii with his pineapple business. Ma and Pa get acquainted with blue-blooded Mrs. Andrews who thinks the Kettles are the "lowliest" people she has met. This is Percy Kilbride's last appearance as Pa Kettle, and his final movie as well.
Cousin Rodney (Loring Smith) has paid Ma and Pa Kettle's way to Hawaii, under the false assumption that Pa is a business genius
who can help increase stalled business at the family pineapple factory.
Pa DOES come up with a solution, although purely by accident.
The Kettles also meet a Hawaiian family who are their "mirror image"---hard working Mother (Hilo Hattie), lazy Father (Lung),
and twelve children named after the months of the year. Pa Kettle is naturally curious as to what will happen when the next child comes
along.
Unscrupulous business rivals kidnap Pa, who remains innocently oblivious of his danger. Both large families converge on the
hideout for a slapstick rescue mission, with Hawaiian food as the chief ammunition.
