Based on a successful real-life youth crime prevention program in Perth, Australia, created by the author, "Ty" is a book and a three-part TV drama that tells the fictional story of Tyrone Lewis, a resilient fourteen-year-old tough London Street kid. Born in jail to his fifteen-year-old addicted mother, Ty's life has been marred by physical abuse, neglect, drug dealing, racism, mental health struggles, youth gangs, and the rising tide of knife crime.

Amidst the turmoil, Ty befriends a runaway pregnant teen abused by her brother. This unlikely friendship leads him into deeper trouble, culminating in his incarceration on various charges, including kidnapping a newborn baby found beside its dead mother in an alleyway. Confronted with the harsh realities of the justice system, Ty's sense of injustice-compounded by his experiences of racism and unfair treatment-fuels his resolve to fight back.

While in prison, Ty climbs the ranks to become a top dog, forming an unexpected bond with Spencer, a bullied transgender inmate who teaches him to read and write. Together, they create an unlikely alliance of misfits dedicated to eliminating makeshift weapons and drugs from within the prison and supporting other inmates with their mental health struggles. Ty's ultimate mission is to reduce youth re-offending, promote safety, and eradicate the pervasive issues of knife crime, youth gangs, antisocial behaviour, racism, and homophobia. Additionally, they aim to extend help to the elderly and disabled who feel like prisoners in their own homes.
