PCs Matt Turner and Rich Woodward are on the tail of an uninsured vehicle. When they finally catch up to the vehicle and question the suspect, they're surprised to discover the driver has never taken a driving test. On the M6, Inspector Anton Sullivan is responding to a collision between a car and an HGV. As the HGV has stopped on a live lane, Anton is tasked with trying to stop traffic, across six busy lanes, while in an unmarked police vehicle.
