 One couple has Henry Elliot (Tom Bosley), a workaholic real estate business man from Cleveland, whose wife, Myra (Marcia Wallace), is trying to get to relax and forget about work, as well as an unaccompanied minor named Robbie (Ronnie Scribner).It is initially assumed the kid belonged to either the Elliots or the other couple on the boat, but neither couple claims the boy (the Elliots mention their kids being back home, and Henry actually forgets how many they have), nor does any other couple staying on the island.Henry continues to fuss over work, despite Myra and the rest of the castaways trying to help him relax, but nothing helps; not a massage, not fishing, not snorkeling, nothing.
