[3][4] Parole officer Sandra Parker (Lois Nettleton) becomes aware of the death of one of her cases, Ginger Stratton, at the hands of brutal prison guard Claire Tyson (Ida Lupino).

Helen gives her boss Barney Fielder (John Larch) the appropriate papers for transporting "Sally Porter" to prison, where she finds herself on Ginger's "ward" and begins asking questions of her other inmates.

Initially unaware of the escape attempt, the prison closes for the night – until Tyson does the usual number checks and sounds the alarm.

As the pair of frantic women are separated, Sally cries out to the governor that she is in fact Sandra Parker, asking him to contact Barney Fielder (Helen's boss) to confirm her identity.

The film ends with Sally walking triumphantly down the corridor which led to her ward – dressed in her ordinary clothes (as opposed to prison uniform).

Leonard Maltin's TV Movies & Video Guide ranks the film as "Average", stating that "Good production tries hard, but script is unbelievable, performances uneven", while the write-up in Michael Weldon's Psychotronic Encyclopedia of Film opens with "The first women's prison TV-movie stars Ida Lupino as a sadistic warden (see Women's Prison of '55)."
