Old Dog: Old Tricks - S3.E9

With stories of children who terrorise pensioners hitting the headlines on a regular basis, tonight's poignant and shocking tale has a very familiar ring to it. Defenceless William Ashurst falls victim to a gang of teeny tearaways who torment him and even tell the police he molested them. Old friend Paul Dangerfield can't believe William's guilty and sets out to help him.

Following the death of his wife, William Ashurst, an old friend of Paul Dangerfield's father, returns to the area of his childhood. Initially regarded with suspicion by the residents of the Foxwood estate, their worst fears are soon realised when Ashurst's dog bites one of the local children. Paul suddenly finds himself embroiled in an increasingly volatile situation as he defends the old man's actions.
