Ocean Girl

In order to continue her research on whales, Dianne Bates is assigned to ORCA. She arrives there to do the research with Dr Winston Seth, but her two sons, Jason and Brett, have to go too and are miserable about the change in scenery. Jason especially does not want to be on ORCA and when he is given the job of tagging a whale, his mother feels he has sabotaged it on purpose - after all, who could believe that a girl appeared in the middle of the ocean?

Vanessa Lane comes to ORCA and ends up in the same class as Jason. Brett, Zoe and Froggy play a trick on Vanessa and she gets back at Brett and leaves him in a broken boat out at sea. A storm comes up, so they can't search for him. He strands on Neri's island and meets Neri, and tells Jason about her when he comes back.

Jason gets his driving license for the boat and goes out to sea to sink a net. Charlie gets stuck in the net and Neri tries to save him but gets stuck also. When Jason realises what has happened he works against time to free them both and Neri reveals a secret place to Jason.

Vanessa and Jason go out on a mission with the boat but Neri warns Jason that an earthquake is coming, so they return. Commander Lucas gets angry but the earthquake is for real and Damien and Lee get stuck in a room leaking water. Froggy pulls a trick with the computer called HELEN which stands for Hydro Electronic Liaison Entity 3000 to try to get them out.

Brett's birthday party proves to be a big hit with his friends but Brett is disappointed when he doesn't receive a gift from his father (his parents are divorced). Following a heated argument between Dianne and Commander Lucas over the acquisition of new equipment for Dianne's research, Winston suggests that they should make an effort to be nicer to one another. Talking with Froggy and Zoe about divorce and stepparents, Brett gets the idea that there may be a relationship at work between his mother and Commander Lucas, especially when he sees how nice they are being to each other of late. Brett's belief seems to be validated when he finds himself being given a private tour of the bridge by Commander Lucas, during which he decides to casually mentions some unsettling details about his mother hoping to disinterest the Commander. After saving Jason from a shark while swimming near her island, Neri tells Jason her life story...that which she remembers.

Jason's frequent use of the boats without completing the tedious, long forms each time results in Commander Lucas banning him from the boats for a week, which would take away Brett and Jason's chance to see Neri. Brett worries that Commander Lucas and his mom are being too friendly, leading Brett to lie to Commander Lucas about his mother, and then to his mother (Dianne). Commander Lucas alters Dianne's request for equipment and only provides her with half of what she needed...she says "just one is usless!" Brett and his friends high five each other after Dianne and Commander Lucas have a fight over the equipment request; they believe that Brett has dodged a bullet: he worries Commander Lucas could become his new stepfather! A pair of eager developers arrive on ORCA unannounced but with documents, expressing an interest in a nearby island-Neri's. Jason volunteers to be their guide on their visit to the island. Before the trio leave ORCA, one of the developers loses his wallet. Jodie wants a $40 tan cream so she can get the attention of a new boy in ORCA. When she finds the wallet, she tries to return it, but the developers are already on the surface. Realizing his wallet is missing, the developer tells the Commander. Jodie "borrows" $40 from the wallet, thinking she'll replace it when she gets her allowance-and then she'll give the wallet back. In the end, the busybody Vanessa finds out that Jodie took the wallet. Vanessa loans Jodie the money so she can turn in the wallet; in return, Jodie must spy on Jason and Brett for Vanessa. Once on the island Jason and Neri develop a plan to scare the developers away from the island. The developers must deal with bees, hands grabbing them from beneath the water, eerie noises, a missing Jason, spiders, snakes, and a crocodile! They fall to their knees in thankfulness when the helicopter finally arrives for them!
