In the first episode of the series, civil enforcement officers in Portsmouth are watching errant drivers. Elsewhere the blue badge investigator looks for drivers using stolen, forged or fradulent disabled parking passes.

In the series finale, Civil Enforcement Officers are patrolling the small city of Hereford. The officers begin to witness some rather unexpected behaviour. In Derby, car-less Mrs Gilby has devoted her life to keeping the residents' car part clear of unwanted visitors. Elsewhere it is back in the Traffic Penalty Tribunal who have seen and heard a wide variety of parking problems. The people of the Tribunal offer their thoughts on the cases they encountered.
