Livvy Haydock explores the secretive world of gang girls, to understand the real stories behind the rising trend in sexual exploitation and violence against girls by gang members - and discovers how quickly female victims turn perpetrators. She enters a gang safe house and meets a young woman whose 'initiation list' included the kidnap and rape of her friend. Livvy also meets a notorious gang girl whose life for the last decade has been dominated by violence – and has lost 30 friends to the streets. These girls are entrenched and traumatized. Livvy asks if it's ever possible to break out of gang life, as she visits Kings College Hospital A&E where a unique project is identifying and reaching young women at a rare moment when they are willing to trust and talk.
