With more than 700 children currently serving prison sentences across England and Wales, the documentary asks why Britain struggles to stop young offenders being sucked into a life of crime. DS Will Whale and his team at Southampton CID investigate 25 burglaries from elderly people's homes, crimes they suspect are connected to a group of teenagers. In Winchester Prison, a young inmate is sent to the segregation unit after climbing onto the roof, while in Hampshire, a probation officer is doing everything she can to keep a prolific offender on the straight and narrow.
