Tim Pigott-Smith (The Vice) stars as Chief Constable John Stafford in this police procedural drama series with a difference. The Chief shows a police force undergoing a culture change, as the outspoken and deeply committed Stafford attempts to reform crime-prevention policies and challenge the frequently unacceptable behaviour of his front-line officers; there are always difficult decisions to be made, often at a professional and personal cost. The cast of this powerful drama series also includes Judy Loe (Casualty) as Stafford's doctor wife, Elizabeth, Eastenders star Tony Caunter, and Roger Lloyd Pack.

John Stafford is back at work at East Anglia's Eastland station following his temporary suspension. While Stafford continues to challenge what he regards as outmoded practices and attitudes, he and his deputy, Anne Stewart, face more tense situations at the sharp end of policing; this second series, originally screened in 1991, sees them tackling animal rights activism and environmental protest, negotiating throughout a dramatic siege, and dealing with the aftermath of the tragic death of one of Eastland's officers.
