The haze that lingered over North Yorkshire, England, lingered for a long time in 1983. On this day, a little girl with an angelic face went missing, which revived people's nightmares that had been forgotten for nearly a decade. In 1974, a little girl named Claire Campree disappeared and was eventually killed. Soon, Mike, with morbid pale cheeks, pleaded guilty. It all seems to be over, and now a similar case is taking place, reminding people of the anomaly of that long-standing case. On the one hand, lawyer John Piggett (Mark Eddie Mark Addy) acts as Mike's lawyer, ready to appeal; on the other hand, police officer Morris (David Morrissey) also reorganizes the old case. In front of them was the darkness as deep and terrible as the night. This film is adapted from David Peace's four suspense novels (title of the year: 1974, 1977, 1980, 1983, collectively known as Red Riding Quartet), and is shot into three films hosted by Channel 4 in the UK, known as the Blood investigation Trilogy.
