PCs Hayes and Fox are called to a suspected fight, but not all is at it seems and they end up trying to get to the bottom of an alleged drug deal gone wrong. Officers Wells and Bace deal with a lovers' spat spinning out of control and need to decide the best course of action to protect everyone, but it's not going to go down very well with either partner.

Officers respond to a report of a two-vehicle crash, but when they arrive at the scene only one of the cars is present, leading them to suspect the other driver has fled as he may have been over the drink-drive limit. In the early hours, an emergency call comes in of a theft in which a man broke into a car, but was disturbed by the owner and is now on the run.

In Gloucestershire police officers are called to a late-night break-in at a shop. Thieves targeting cigarettes have raided the premises and made off at high speed, initiating a force-wide area search across the county with the police helicopter joining ground units to track the gang down. Traffic officer PC Webb, aka "Bear", is on the M5 motorway dealing with torrential rain which is making driving treacherous. He's called to a crash in the fast lane that has brought traffic to a standstill and is causing a headache for the cops and rescue crews. Near Cheltenham, two PCs deal with a problem: a driver has called in to report another road user for drink driving, but when the cops arrive it's the man who reported it who seems drunk and who is breathalysed, and found over the limit. However, the biggest issue for the cops is his aggression, and his tactics delay the inevitable breath test back at the station. And PC Dawkins notices a van driving along with the passenger door open. As he pulls up to investigate, a passenger runs off leaving the driver to explain what is going on.
