Bea Smith and the other inmates find out about Frankie's plans to get paroled and live on a farm so they try to rile her into blowing her chances.

She goes back on the game to buy Eddie a birthday present, prompting them to have a row and she walks out on him. Helen Masters is sent to Wentworth charged with manslaughter after her car is used in a hit-and-run. At first she is to be bailed but when she tries...

Marilyn's boyfriend Eddie is suspicious of where she got the money for his birthday gift: back "on the game" (prostitution)? The final straw is a visitor who is obviously a "workmate" from the street. Officials and inmates are puzzled when Helen Masters drops her application for bail. She uses the media to bring attention to the "innocent" women being incarcerated--including herself, of course. The Bentleys, the culprits responsible for Lyn's conviction, continue their libertine ways, but are finally exposed and arrested.

Helen Masters sets out to affect the quality of prison meals as part of her campaign to get a character witness for her trial, the prison doctor. Marilyn returns to prison, but Eddie is through. Vera's drinking almost gets her arrested in a pub, but the officer grants her professional courtesy and takes her home. Masters cons everybody--even her blackmailing assistant--and wins acquittal, trashing the prison officials and inmates in her first TV interview.

The inmates start realigning after Master's release; Frankie gains motivation from her brother to work on good behavior. Lyn, who has returned to her parents' home, runs away with Doug whom she had met while in prison. A detective, pretending to be attracted to Vera, interrogates Marilyn about her associates and their drug connections. Frankie, who can't read, gets a telegram saying her brother was injured and goes berserk when it's read to her, deciding to end it all.

Vera's attitude continues to become more punitive toward the inmates, bringing a reprimand from the governor. Lizzie's heart forces her to return to the prison, while Frankie and Doreen face life on the run with no money. Lyn faces the fact that Doug is still a criminal, and she reluctantly gets involved in a holdup.

Shot in the holdup, Doug dies and Lyn cannot run, so she calls the prison doctor who gets there just before the cops. She loses her baby. Doug gets sacked because of his involvement with Marilyn. Frankie and Doreen are still on the run. The new social worker visits Mum's granddaughter and explains how much Mum needs to see her.

A new prisoner, who is reputed to be really tough, is admitted; she and Bea turn out to be old friends, dashing Vera's hopes. Lyn is returned to prison.
