A film which dives into the controversy that surrounds ABA (Applied Behaviour Analysis) which is an intense intervention used to treat children who have autism, a lifelong developmental disorder which affects around 1 percent of the population in the United Kingdom.

ABA uses a system of rewards and consequences to modify behaviour, it is based on the discoveries of psychologist B. F. Skinner and his experiments with rats and pigeons at Harvard University. ABA was first applied to children with autism in California in the 1960s and 70s, ever since it first appeared it has raised questions about the rights of children with autism.

ABA has changed radically since its early experiments and is now used widely in the United States but not in the UK were there is only one school offering a full ABA program, Treetops. This film follows three-year-old Jack and four-year-old Jeremiah through their first term at here in order to see how they progress when immersed within the questioned treatment.
