First in a two-part documentary following the work of High Close School in Berkshire, a residential and day school run by Barnardo's that looks after children with a range of emotional and behavioural difficulties. Twelve-year-old Courtney from Liverpool has been diagnosed with ADHD and was excluded from primary school for disruptive behaviour. Although her key worker believes she has great potential, as she approaches her teens, the girl's behaviour is deteriorating fast. The film looks for clues to Courtney's anger in her family history and sees whether the school can turn her life around.
