Chadwick Gates (Elvis Presley) has just gotten out of the Army, and is happy to be back in Hawaii with his surfboard, his beach buddies, and his girlfriend Maile Duval (Joan Blackman). His mother, Sarah Lee (Angela Lansbury), wants him to follow in his father's footsteps and take over management at the Great Southern Hawaiian Fruit Company, the family business, but Chad is reluctant, so he goes to work as a tour guide at his girlfriend's agency. His slightly scatter-brained boss is Mr. Chapman (Howard McNear).
