Episode 4 (S01E04)

Officers chase down suspects who used a crowbar and an air rifle to rob a civilian. When the pursuit leaves the road, the police helicopter is called in for backup. PCs John Douglas and Joe Gorman notice a BMW speeding ahead, and as they pull up behind it, the worn rear wheel throws off sparks against the asphalt. Meanwhile, in Hull, PCs Susan Scott and Rich Starkie rush to the scene after reports that a pedestrian has been hit by a car.
