Zenon aspires to attend the Moonstock music festival, and to that end she enters the Galactic Teen Supreme Contest. Zenon thinks that the only roadblock to her success is her snotty rival Bronley Hale, but soon she finds herself sidetracked by the efforts of space ecologist Sage Borealis to prevent further colonization of the Moon. As it happens the problems of Bronley and Sage don't amount to a hill of beans when a hitherto unsuspected villain appears, intent upon destroying the universe. (allmovie)
