"Wacko" - a fast-moving comedy - voluptuous nymphets, young studs, the 'last virgin in the school', a bald looney and an obsessed detective (who hasn't slept in thirteen years) are all involved in various satirical scenes from such films as 'Alien', 'Saturday Night Fever', 'Grease', 'Dr Moreau', 'The Exorcist' and 'Dr Strangelove' and plagued by the return of the infamous 'Lawnmower Killer' who makes his final appearance at the High School Pumpkin Prom thirteen years after his first fatal attack.
