Catherine Cawood is a sergeant in a small town in West Yorkshire that is riddled with a drug culture that is daunting to tackle. Kevin Weatherill is an accountant in a large company run by his late father's best friend, Nevison. When Nevison refuses to raise Kevin's pay so Kevin can afford to send his daughter to a better school, something Kevin believes Nevison owes him, Kevin orchestrates with local thug Ashley Cowgill a plot to kidnap Nevison's daughter, Ann. Cowgill involves his employees, Tommy Lee Royce and Lewis Whippey, and changes the terms, causing Kevin's scheme to backfire. Sergeant Catherine Cawood lives with her recovering heroin addict sister and brings up her eight-year-old grandson, Ryan. Whilst visiting Ryan's teacher regarding the boy's behavioural problems, Catherine reveals her daughter was raped by Royce. She believes this rape drove her daughter to commit suicide shortly after giving birth to Tommy's son, Ryan, whom Catherine has raised alone ever since. The episode ends with a very anxious Kevin entering Catherine's West Yorkshire police station to report the kidnapping, but he changes his mind at the last minute.
