Four Corners exposes what happens behind closed doors in some taxpayer funded group homes for the disabled and talks to the mothers and carers taking on the system. These are families who've made the tough decision to place their disabled children into care, in the belief it would be the safest place for them. They say their trust has been betrayed. This Four Corners investigation shines a light on the mistreatment of these vulnerable people. These are homes where sexual and physical abuse occurs and perpetrators get away with it, because police and the justice system are unable to cope with the challenges of dealing with witnesses with disabilities. One industry watchdog expresses his frustration over the failure of the group home operators to end the mistreatment. And despite the billions promised for the National Disability Insurance Scheme and plans for new protections, some warn that families need to stay vigilant. The mothers and carers who've seen their children come to harm are determined to speak out and demand action.

Four Corners is Australia's premier television current affairs program. It has been part of the Australian story since August 1961, exposing scandals, triggering inquiries, firing debate, confronting taboos and interpreting fads, trends and sub-cultures. Its consistently high standards of journalism and film-making have earned international recognition and an array of Walkleys, Logies and other national awards.
