Gerry Sont (best known in Australia for the television soap, Waterloo Station) plays the virginal Melvin, who works as a teenage car-wash attendant.
He is irresistibly attractive to women but cannot understand why – as he does not realise he is the son of Alvin Purple – and has grown up deathly afraid of women.
Melvin becomes friendly with a Greek usherette, Gloria (Lenita Psillakis), who rescues him from marauding women and becomes his well-meaning girlfriend.
Eventually, a reunion of the Purple clan takes place where all is revealed.
Graeme Blundell reprises his Alvin persona, now sadly middle-aged and burnt out, working as a singer in a purple jumpsuit on the Club circuit, singing schmaltzy ballads to his adoring women fans.
In thankless support roles, Tina Bursill as crusading 60 Minutes-style reporter Dee Tanner and David Argue as her bumbling cameraman, are teamed as comedy relief as they set out to reveal that Alvin is being exploited by his seedy manager Burnbaum (Jon Finlayson) and that he is the long-lost father of Melvin.
Before the movie’s release, three cuts were ordered by the censors – the offending material contained nudity and a simulation of oral sex. What remained in the final cut was innocuous enough to ensure a brief theatrical run and public indifference.
