Denny Miller guest stars as Duke Williams, a musclebound surfer who has washed ashore on the island after riding a huge tsunami all the way from Hawaii. Naturally, the castaways are certain that Duke will be able to rise another big wave back to civilization and arrange a rescue. Unfortunately, now that he has had a good look at the toothsome Ginger (Tina Louise) and Mary Ann (Dawn Wells), Duke is no hurry to return home!
