In Cannock, PC Ade Cash joins the hunt for a Mondeo that's failed to stop for police. When another unit gets behind it, the driver makes off - reaching speeds of 80mph in a 60 zone and crashing into other motorists. On the M6, PC Mark Gribble is training PC Aaron Hardy in the art of spotting dodgy drivers. Aaron clocks a dog in the driver's seat - a first even for Mark.
