S3E9 Old Dog: Old Tricks

In a world where stories of children menacing the elderly frequently make the news, tonight's disturbing narrative feels all too familiar. Helpless William Ashurst becomes the target of a group of unruly teens who harass him and falsely accuse him of molestation. Paul Dangerfield, a longtime friend of William, refuses to believe the allegations and vows to assist him. After losing his wife, William returns to his childhood neighborhood, but the residents of the Foxwood estate view him with suspicion. Their fears escalate when Ashurst's dog bites a local child. Paul finds himself drawn into a tense situation as he defends the elderly man’s actions against rising hostility.
