When Bill Hixon (Rob Lowe), America's Top Metropolitan Police Chief three years running, lands in Boston, Lincolnshire, with his 14-year-old daughter Kelsey in tow, he's hoping they can flee their painful recent past. Bill soon discovers that the people of this unfamiliar community are just as smart-mouthed, cynical and difficult to impress as he is, and, as a man who's spent his life keeping the messiness of human intimacy at arm's length, he is reluctantly propelled into frontline policing.
