Station Sergeant Barlow is back, but if he thought life was going to return to normal after his last case, he couldn't have been more wrong. Barlow's house is bombed, and he is suspended from duty on suspicion of Perverting the Course of Justice. His problems mount when his schizophrenic wife is released unexpectedly from the mental institution and he learns the truth about her traumatic childhood; while his daughter, Vera, is shot during a robbery. He is under strict orders not to interfere in the ongoing investigations, but shooting Vera has made it personal.
