London-based pop group Toomorrow, fronted by Olivia (Olivia Newton-John), are abducted by aliens to save their race from extinction in this rarely seen sci-fi musical.
The group are attempting to pay their way through college with their music. Unbeknownst to them, the sonic vibrations from their ‘tonaliser’ have been picked up by the Alphoid Galactic Control and identified as the only solution to saving the Alphoids from extinction.
