England and Wales hold more than 80,000 prisoners, and the film's starting claim is that a striking share of them passed through some form of government-funded institution before ever reaching a cell, from children's homes to the care system. Building on that statistic, the documentary follows the thread from institutional upbringing to incarceration, using interviews and case accounts to trace how early state intervention in a child's life can become a pipeline toward later imprisonment rather than protection from it. The film stays within the British criminal justice and care systems, examining what happens to children once they are removed from their families and how those early years echo through later contact with police, courts, and prisons. It is less concerned with individual crimes than with the institutions meant to prevent them, asking what the state owes children it takes into its own custody, and what it costs society when that duty goes unmet.
