Six years after his first visit to Yorkshire, England, detective Peter Hunter (Paddy Considine) returns to look into the town's high murder rate. Though the deaths have been occurring with alarming regularity over the years, the police have done little to find the killer, who's now known as the Yorkshire Ripper. As Hunter discovers mysterious irregularities in the case, he realizes corrupt police officers (David Morrissey, Warren Clarke) are doing everything they can to stop his investigation.
