The Shongili twins Ronan & Murel accompany their friend Marmie on her luxury space craft Piaf to rescue their friend Ke-ola's family from an uninhabitable planet. They arrive to find the planet in the midst of a terrible meteor storm & when they go down to the surface find that the survivors have taken refuge under ground. Ronan & Murel change into seal form & find the survivors & their totem animals or aumakua the giant turtles or Honu & the sharks. Back on Petaybee the twins in their seal form escort the Honus to their new home in the middle of the ocean. They also want to warn the otters & seals about the sharks. It is a long journey & Murel falls asleep & gets separated from the rest. She is surrounded by a pod of Orcas who thinking she is a normal seal try to eat her. Before they can do so she is caught up in a whirlpool caused by the volcanic activity in the area as is Ronan who had swum back to try to rescue her. They are rescued from the whirlpool by the mysterious deep sea otters & taken into their shielded city on the ocean floor. While their leader Kushtaka is talking to them her son Jeel sees the sharks & goes to inspect them Murel races after him but is too late & Jeel is killed. Meanwhile Marmie & her crew are arrested on trumped up charges of kidnapping Ke-ola's family & taken to Gwinnett Incarceration Colony along with most of the survivors they rescued. When Murel & Ronan return to their family & discover that Marmie has been arrested & the Piaf impounded they realize they need to get off the planet & go to her rescue. While staying with Kushtaka they were told that the deep sea otters were not just otters but beings from outer space who had hidden in the depths of Petaybee's oceans for years. Now that they have been discovered they plan to leave the twins persuade Kushtaka to take them with her & to help them rescue Marmie.
