Ocean Girl

Jason and Brett eagerly await the return of Neri and Charlie-as does UBRI's Dr. Hellegren who wants to study just one of the returning humpback whales, Charlie.

Neri makes her first visit to ORCA since her return, and tells her friends that she wants to discover who "her people" were. Jason, Brett and Neri go to her island to look for clues to her identity.

The gang begins to dig for Neri's spaceship on the beach on part of the island Neri has never visited. The gang seem to be finding a huge spaceship and Neri brings Jason to the entrance of the ship deep under water.

The search for Neri's sister Mera is underway. Mick asks Froggy to use his computer to change his grades but Froggy won't do it. Commander Byrne isn't pleased with her son's grades but Mick once again charms his way out of trouble.

The kids locate Mera. Her adopted name is Jane Seaforth, and after being bounced from foster family to foster family, she is now living at an institute for gifted children.

Jason, Brett, Froggy, and Zoe return to the institute to get Mera but Dr. Hellegren arrives there as well wanting to take Mera back to UBRI with him.

Mera is having a difficult time adjusting to living on the island and Neri leaves her alone while she goes to help with the survey again. Mick gets Froggy to use HELEN to spy on Vanessa's counseling session.

Suspecting a connection between Neri and Jane Seaforth, Dr. Hellegren sends UBRI agents Forsyth and Liselle to ORCA to learn as much as they can about the two girls.

Neri returns to help Dianne with her oceanographic survey leaving Mera alone on the island to face a UBRI search party that has come to the island looking for them.

Prior to leaving on the final survey mission, Dianne learns Commander Byrne has assigned Froggy, Zoey, Joanne, Rocky and Kimberly to her crew. Forsyth hides a transmitter on the boat to allow UBRI to follow it.

Jason takes Neri and Mera swimming off the ORCA platform. Mick finds out and heads out on a jetski, he falls off and must be rescued by the girls. Neri helps Mick with his reading, he in turn joins the others in keeping Neri and Mera a secret.

Neri leaves ORCA intending to save Mera and Charlie by giving herself up to UBRI. Brett chases after her, gets into an accident with a UBRI boat and is saved by Neri.

Neri and Mera make the decision to return to the Ocean Planet and convince Diane that her research must continue. Froggy fixes HELEN, with a little help from Damien. Commander Byrne has Forsythe arrested when HELEN identifies him as the saboteur.
