A Prayer Before Dawn is the remarkable true story of Billy Moore, a young English boxer incarcerated for three years in two of Thailand’s most notorious prisons. He is quickly thrown into a world of drugs and gang violence, but when the prison authorities allow him to take part in the Muay Thai boxing tournaments, Billy realises that this is his only hope for survival, taking him on an incredible journey to redemption.

A Prayer Before Dawn is out in cinemas from 20 July.
