[Part 1] Filmmaker Saskia Baron has unique insights into autism. Her older brother, Timothy, is profoundly autistic. When he was diagnosed in 1961, his parents found that there was no education available for children with autism their fate was mental handicap hospitals and sedation. Unwilling to accept such a prospect, Timothy's parents got together with other families with autistic children and started the National Autistic Society in 1962. Together, the parents established the first school in the world for autistic children in 1965. Using a recently rediscovered film of that school, the documentary explores how life turned out for the first generation of children to be diagnosed with autism in Britain.
