Documentary revisiting John Davidson, who featured in a BBC film about Tourettes syndrome in 1989 (John’s Not Mad), and 15-year-old Greg Storey, who the cameras met when they revisited John in 2002.
Greg is now the same age as John was when he first took part in a documentary. How does Greg’s experience of being a teenager with Tourettes compare to John’s, and how does John’s life continue to change?
