Conviction is a British television crime drama that premiered on BBC Three on 7 November 2004. The six-part series stars William Ash, David Warner, Ian Puleston-Davies, Reece Dinsdale, Nicholas Gleaves, Laura Fraser, Jason Watkins and Zoe Henry.
The series is centred on the Fairburn family, all of whom live in an edgy Lancashire town with a growing tendency towards vigilante justice. All three of the Fairburn siblings are involved with law enforcement: brothers Chrissie (William Ash) and Ray (Nicholas Gleaves) are police officers, while their sister Beth (Zoe Henry) works as a lawyer. Beth, Chrissie and Ray's widowed father Lenny (David Warner) is a retired police officer who berates the political correctness of his children's modern methods: he himself is fighting a losing battle with Alzheimer's disease and struggling to come to terms with the fact that he can no longer be the strong and authoritative head of the family.
