The Flying Doctors - Season 1 Episode 7 Square Pegs

Andrew Cameron is a farmer and very successful in everything he does. He demands his son, Matt, to be just as successful as he is, which of course is impossible. Finally Matt breaks into the Nomad and steels some drugs and tries to kill himself. He is rescued by the RFDS though. Tom finds an old woman, Ruth Pitt, in a tent outside town, where she lives with her retarded son Hugh. Ruth has a bad heart, and she dies, so they have to send Hugh to a home. It feels a bit sad, since everybody liked him so much.
