The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'JOHN NOBLE: Thirtyish. He hit the big-time as a pop singer a few years ago, made money with a splash but spent it just as fast. Then suddenly his popularity was over. And he couldn't accept that. He was a god, now he's expected to be just an ordinary bloke again - take a job at low wages, buy a house in the suburbs. So he won't admit he's finished. He drinks too much, is ready to steal money rather than work for it. But that's better than being a nobody, going nowhere. (Actor must be able to drive.)
'JENNY NOBLE: Noble's wife. Mid-twenties, a youthful, sensitive girl. She met John when his popularity was waning; now she's deeply in love with him, despite his faults. Just pregnant, she wants security for herself and the baby. Wants to live like any ordinary family. That's all she asks.
'BEN LIPSON: Fortyish. A criminal type, an experienced safe breaker who has previous convictions and has 'done time'. He is ready to sell out his mates when things get tough for him. But outwardly he's hard, tough looking. (Actor must be able to drive.)
'CONSTABLE RON HALL: Police constable established in earlier episodes. A humorist.
'TRUCKIE: Rough, burly, the kind of man who doesn't mind running drugs down from Sydney to make a bit on the side. Does his job, expects to get paid on delivery. (No actual driving scenes)
'JENNY'S SISTER: A doctor's wife; older, more sophisticated, more durable than Jenny. And protective towards her younger sister. (Actress must be able to drive.)
'TONY TODD: Mid-twenties. Smooth young man, ex-manager of a pop group - he was exploiting teenagers even when he was one himself. He's ambitious, and sees himself as a 'Mr. Big' in the world of drug trafficking. He runs a disco and sells drugs on the side, through his pushers.
'RICHARD RICE: Late twenties. 'Mod' - a musician who's been pushing drugs for Tony Todd. A bit soft physically, a 'mother's boy' but smooth and clever and sly too.
'WAITRESS (YOUNG GIRL): Eighteen or nineteen. Serves coffee at the disco. Has a habit of overhearing conversations and passing on interesting bits of information to Tony Todd. No dialogue.
'TEENAGE EXTRAS: Kids ranging from sixteen to twenties who are enjoying the music and the crowd at the disco.
'BERT GOLDING (CLUB MANAGER): Middle-aged. Smooth, plump impresario type. His business is making money from singers and groups. When they're washed up, he doesn't want to know them.
'DWYER'S GIRLFRIEND: A pretty, typical teenager who enjoys a good time. No dialogue.
'YOUNG COUPLE: Boy about eighteen, girl barely sixteen. 'Nice kids' caught courting in parked car by the police. Boy able to drive.
'OTHERS: Uniformed constable, and wood splitter (at fuel merchant's yard). Both actual.'
