Bob Trebor joined the police in the seventies. After showing a natural talent for catching the bad guys, when a vacancy rose in the CID, he jumped at it. At the age of twenty-nine, he is the youngest Detective Inspector in the country - and he has a vision of what he wants his squad to be.

His journey continues through his particular style of recruiting to his squad, and his philosophy, having inherited a bunch of deadbeats, the pickpockets or sometime knife-point robbers, scourge of the public using the underground network needed regular culling. Whilst the means justifying the ends are questionable, there is no denying those in positions of power and judiciary are quite content. What's distinct from previous squads selected for the task is their pleasure in just nicking the villains straight, without indulging in financial corruption, or taking a bung, referred to as 'taxing' and 'giving a life' to the criminal.

But when a plain clothes police officer is badly assaulted, this sets off a chain of reaction, ultimately ending in a tragic death and multiple allegations of widespread corruption. With Internal Investigations sniffing around, the criminal fraternity looking for revenge and a squad on the brink of collapse, it looks like Bob's philosophy could be faulty. Will it be Internal Investigations that wins the day or will Bob defeat one last 'bad guy', whoever that may turn out to be?
