Return of the documentary following Gloucestershire Constabulary on the night shift, beginning with a busy Saturday for PC Hewer on patrol in Cheltenham town centre. Among the crowds of drinkers, Hewer challenges a man suspected of urinating in the street, who then becomes abusive.

Officers race to catch burglars red-handed after two men are seen trying to break into a number of houses in Cheltenham. When the cops arrive, the men have disappeared, but an extensive search reveals a suspected stolen moped, and police dog Elmo picks up a strong scent and starts tracking. In Gloucester, traffic cops are pursuing a dangerous suspected drink driver. As officers race to catch up, two innocent female passengers are caught up in the nightmare 120mph chase as he speeds through a red light and drives the wrong way around a roundabout. Officers close in on the driver — before he suddenly brakes and tries to flee on foot. Suspicions are raised when a man pulled over for a minor traffic offence becomes irate and argumentative. Gloucestershire cops suspect the man may be high on drugs, and a subsequent drug test provides a surprising result for the driver. As officers take their suspect in for questioning, the man is seen acting suspiciously in the back of the police car and officers find two suspicious packages. A manhunt is launched after a driver smashes into a gas main and disappears into the night. As officers investigate the crash, a car is found in a ditch, but the driver is missing. Police officers fear the driver may be injured, and a police helicopter joins the search. But then new information from control takes the investigation into a surprising new direction. A suspected drink driver is at fault when a car is left abandoned after a late-night accident. A man found propped up against a tree claims he isn't the driver and that his facial injuries are the result of a pub fight. But the cops are not convinced and start investigating.
