Hank discovers that Sean had broken into a satellite research center in order to boost the signal of a code he'd received by someone he suspects is Alexander Anderson, Sean's grandfather who had been missing for two years. Wanting to bond with his stepson the next day, Hank helps Sean decipher the code of Jules Verne characters which lead to three books: Treasure Island, Gulliver's Travels, and Verne's own Mysterious Island. Using the book's individual island maps, Hank suspects they are books of the same island and uses a back light in order to make them all one completed land mass with the coordinates to its location. Hank manages to convince Liz to let the both of them go in search of the island. They arrive in Palau where their need of transportation to this dangerous part of the ocean attracts an Palauan helicopter tourism guide Gabato (Luis Guzman) and his daughter Kailani (Vanessa Hudgens) who Sean develops an immediate crush on. They agree to fly them out to the island for $3,000, but the helicopter gets caught in a category 5 hurricane and they crash into the Pacific, waking up on the island.
