Come with Angela Kirwin for a journey inside prison like no other. For over a decade she was a social care worker in some of Britain's most notorious prisons.

Now she wants to tell the stories of the men she met, because she believes that prison is failing everyone, damaging the most vulnerable people in our societies, creating habitual criminals, leaving us all less safe and contributing to a society that is immeasurably less humane. Every year, we spend billions of pounds on a system that fundamentally doesn't work.

Rather than a separate world full of people that aren't like us, prison is where the most damaged and vulnerable people in our society end up and we all need to urgently care about that, so we can change it. Because the state of our prisons is criminal.
