Each week viewers see the gritty reality of life in a New York City Police unit as the officers go about their work with a grim determination. Two partners, Detectives Andy Sipowicz and John Kelley (later replaced by Bobby Simone), are the central characters in this weekly police drama, and personify very different approaches to their difficult job. Sipowicz's brash gruffness (covering an emotional vulnerability) is tempered by the precise and controlled demeanor of the two partners with whom he has worked.

DCI Gill Murray, DC Janet Scott, DC Rachel Bailey find themselves working alongside the formidable DCI Julie Dodson when two badly burned bodies are found in remote woodland.

Janet is promoted to sergeant but steps down to give it to Rachel as she feels she is needed more at home. The pair join the search for eighteen year old Robin McKendrick, a simple lad reported missing by his boss, landlord John Rivington. Pub regulars are unforthcoming until a boy called John tells Janet that an ex-soldier known as Jackie-Boy locked Robin in his car boot as a cruel prank. He later reported the car as stolen. Another witness claims that Jackie- Boy dumped his car in a quarry with Robin still in the boot. In the process of the investigation Gill identifies another body found in the river, that of Mandy Sweeting, who disappeared two decades ago.
