Kent's vigilante actions on the Cole Lane Estate could be his undoing when one of his supporters, Laura Bryant, decides he's crossed the line, and reports his actions to Thatcher. As Thatcher and Drummond follow up Laura's allegations, Kent's accomplice Kev is found beaten and locked in the boot of a car. Drummond sees Irene Radford, head of a ruthless crime family on the estate, and it looks as though the Radfords are running a protection racket. Tait dives into the Thames to rescue the two children from the sinking car. McAllister leads a raid to arrest an aggravated burglary suspect, and Nixon realises he fits the profile of their serial rapist. Hunter returns to work, but makes excuses due to his injury.
