The Last Chance

A large quake prompts the commander to call for an evacuation of all ORCA personnel under the age of 18. Dr. Hellegren is putting the Synchronium together when Kal demands that he be made the ruler of Neri's island as he was promised, Hellegren again brushes off Kal and has him escorted back to his room. Anxious to get the Synchronium back from Dr. Hellegren, Neri goes to get Jason. He is out on a dive mission with Sallyanne, and when Neri surfaces Sallyanne is there to see her. Angry about the way he is being treated by Dr. Hellegren, Kal attempts to steal a piece of the Synchronium, he is quickly caught by UBRI guards and taken back to his room. Back on ORCA, Sallyanne is introduced to Neri and Mera and plans are made to recover the Synchronium. Getting away during the confusion surrounding the evacuation, the kids are able to make it to UBRI's pier on the mainland. However, they are soon spotted by Kellar and are left tied (Dr. Hellegren taking Lena with him) up as the UBRI vessel heads out to sea. Kal escapes from UBRI and arriving at the pier, he unties the others. As Dr. Hellegren prepares to activate the Synchronium, Neri and Mera surface and plead with him not to proceed, even offering themselves for his to study if he stops. With her father preparing to unleash the power of the activated Synchronium, Lena jumps into the now seething and churning ocean to force him to stop or risk killing her as well. As Hellegren hesitates unsure what to do, Kellar pushes him aside to lower the Synchronium into the ocean. Just before it impacts, Kal surfaces and grabs the Synchronium and with Neri and Mera take it back to the island as a dejected Dr. Hellegren must admit defeat. Back in the safety of the island, Neri and Mera activate the Synchronium reversing the damage done to the Earth's oceans. Neri and Mera make a final trip to ORCA where Dianne and Winston are told about the Synchronium. After saying their goodbye's, the girls return to the island where Kal and Mera board a spaceship which lifts off taking them back to the Ocean Planet.
