In the third installment of the hit Zenon trilogy, it's 2054 and Zenon Kar is 17 and competing to win the Galactic Teen Supreme contest--against handsome competitor Bronley Hale--and celebrate at the Moonstock Festival. She also reunites with Moon preservation activist Sage Borealis, who is desperate to keep the Moon from being colonized and exploited and wants Zenon's help. Meanwhile, Commander Edward Plank and Aunt Judy Cling's new foster daughter Dasha is starstruck by Zenon and finds staying out of trouble difficult. During the last competition for the Galactic Teen Supreme contest, moon goddess Selene appears and threatens to destroy the Earth, and Zenon must save everyone from this angry deity. It's up to Zenon to save everyone from this angry deity. In the end, Zenon, Sage, Bronley, and Dasha and her friends Margie and Cassie team up to evacuate everyone in Protozoa's tour bus and try to remove the Moon Dome, with each taking a hover pod. Unfortunately, the dome is too heavy until Commander Plank and Aunt Judy show up looking for Dasha. They're able to help lift the dome and send it drifting into space. Selene then destroys the rest of the base and waves goodbye as the friends return to Earth. Selene stops the wild weather she caused, Zenon and Sage kiss, and Protozoa's band Microbe and the new hit band Cosmic Blush hold a concert. Written by Anonymous
