Following on from the success of the award-winning ABC television series Choir Of Hard Knocks, choirmaster Jonathon Welch is on a mission. He believes music can change lives and he's out to prove it. This four-part series is a journey of participation and transformation in an unfamiliar world and humanises those on the inside. In an unprecedented move, Corrections Victoria has allowed Jonathon to begin a choir inside Tarrengower Prison, a low security women's prison in regional Victoria. It's the first time a documentary series has been filmed in a Victorian prison. The prison and Jonathon share an objective: to restore the prisoners' self-esteem and improve their rehabilitative prospects. But can Jonathon's song and dance routines have any lasting effect on these women?
