Officers in Harrogate spot a youth behaving suspiciously, but when they try to stop him, he flees into a local housing estate and things rapidly escalate as a hostile crowd gathers. On the southern border of North Yorkshire, some more youngsters catch the eye of the traffic cops when it appears the driver is using a mobile phone. As they attempt to pull the car over, the suspects speed off and the chase is on. The police conduct a raid on a house near York, on the hunt for a suspected drug dealer, while a routine patrol takes a sinister turn when a man in a bar is spotted with a knife.
