In "Ex Plus Y," newlyweds Terri and Ron Larson (Loretta "M*A*S*H" Swit and Richard "Soap" Mulligan) are adjusting well until Terri encounters ex-husband Barney (Robert Reed) aboard ship with his lady friend. "Graham and Kelly" is about a 13-year-old girl (Kristy McNichol of "Family") and boy (Scott Baio) who feel love for the first time, face its hardships, then see it blossom. Cruise director Julie McCoy is attracted to handsome Die young Jim Wright (Charles Frank) who is conducting a Life Begins-at-Sixty tour in "The Goldenagers." But the active senior citizens leave Jim little time for romance.
