Ross and Arthur are helped by Karara and two trained dolphins in Hawaika, which was settled by Hawaiian and Polynesian settlers. The planet Hawaikan is a warm tropical planet that is mostly ocean. It is so different from what they had expected that they decide to risk a time trip back in the planet's history. Just as they are about to use the time gate a storm blows up and Murdock is flung through the gate and into the planet's past.
