Officers are on the lookout for a suspected cloned car, a vehicle disguised as another by copying its number plate, as they believe it is being used to commit crime. When it's spotted, four suspects make a run for it, and one is recognised as someone who rammed a police car weeks before. On the M1, officers tail a car linked to a known repeat offender and as several units pull over the car, the driver suddenly jumps into the back seat. Searching the vehicle, the cops make a worrying discovery.
