Jenny Langby, mother of five children, lived in Port Adelaide, South Australia. At the age of 32, she was dead.

Who Killed Jenny Langby? This film, in documentary format, is about the events which led up to Jenny Langby's death, There were numerous extraordinary pressures upon Jenny . . . her insensitive and often drunk husband, her eldest son in trouble with the police, her asthmatic six-year-old daughter, her live-in and quick-to-criticise mother, and her own Sack of free time to get away from housework.

The sum of these parts was greater than the parts taken individually, and Jenny Langby took her own life to escape.
