Evil Eva and her cronies threaten to blow their enemies sky-high by reactivating the Rangitoto volcano with a nuclear device. However, the goofy gang isn't all bad - they like to break into song and dance while holding the city for ransom. Who will save the city from destruction? Why a talented trio of kids, including a nutcase who has invented an antigravity machine. The police force, zonked out on Eva's drugged coffee, are made ineffectual.

Governor Wilkins brings rookie cop Lucille Bromley to see the imprisoned cannibal Dr Genghis in order to gain information about a serial killer.
