What happens when a Rangers fan and Celtic fan are locked in a prison cell together on the day of an Old Firm Match?

It is through Billy and Tim that Des Dillon explores sectarianism, bigotry, how it becomes part of one's identity and is inculcated by family and society. However, the book is not limited to Scotland but refers to every peace process in the world, where common ground and a shared humanity is found through responding to the needs of others. Now it is up to these two fans to start their personal peace process to find some common ground to slowly let go of their bigotry.
