When a former vice cop is discovered beaten to death in an underpass, DS Ronnie Brooks and DS Matt Devlin find their investigation going in unexpected directions.

A convicted murderer who has been studying law inside is given the chance to appeal and chooses to represent himself in court against James Steel - his former prosecutor.

Was the arson attack on a Turkish club claiming 17 lives racially motivated - or something even more sinister? James Steel and Alesha Phllips struggle to build the case.

A police officer is killed in a shoot out with a drug dealer. Based on the testimony of another dealer, Brooks and Devlin must determine whether back up was slow to arrive and left the officer to die because he was gay.

A drug sting apparently goes bad resulting in the death of an informant. Devlin feeling something was not right about the situation digs into the past of the involved detective. Unfortunately this brings up a question of Brooks involvement in a drug theft from six years earlier.
