The Kettles (Marjorie Main and Percy Kilbride) find themselves in uncharted territory when they travel to Hawaii in Ma and Pa Kettle at Waikiki. Pa's been summoned by an ailing relative (Loring Smith) to operate his pineapple factory until he recovers. In no time at all, tycoon Pa increases production (by accident, of course) and comes to the attention of a jealous business rival. From then on, it's every man for himself. Using their well-honed skills, Ma and Pa create hilarious havoc that needs to be seen to be believed!
