The series starred
British Chinese actor
David Yip as Detective Sergeant John Ho. Yip became the first Chinese lead actor in any British television drama series. The series offered traditional police procedural storylines in a setting of occasional prejudice and distrust within the police force, and the prejudice displayed by those Ho encounters whilst doing his job. Like many other television detectives of the time, Ho was something of a maverick, often using unorthodox methods to solve crimes. The series was set in and around London's
Docklands, before
redevelopment began in the 1980s. His immediate superior in the force, Detective Chief Inspector Berwick (
Derek Martin), often provided him a source of stress, often reprimanding him for his approach towards the cases he was investigating. Ho is also often seen visiting his father, Joe (
Robert Lee), for advice at the
shipping container plant where he worked. Like many other television detectives of the era, Ho drove a 'classic' car. In this case, Ho's vehicle of choice was a
Morris Minor Traveller. ==Cast==
