Stritch and Monroe clash over a series of new timekeeping 'exercises' being implemented to improve response times. Meanwhile, Loxton and Slater manage to catch up with a group of racist attackers whom CID are desperate to nail. As they give chase into a derelict building, Loxton becomes involved in a fight with one of the suspects, who steps through an open door and falls to his death. Stritch soon finds the relief laying the blame firmly at his door.
