When a car is stolen Officer Jeremy Ryan and his K9 partner Ranger are drawn into a high speed car chase across the city. The teenage driver loses control, he crashes and bails from the car; he runs on foot and K9 Ranger is on his tail. Also, Officer Nicole Rasmussen and K9 Chase close in on a wanted man and the K9 cops help to take a drug dealer off the city streets when K9 Rico follows his nose to a hidden stash of Heroin.
