In this week's episode, PC Andy Doran is making his way to the scene of a collision on the A6, where a tired young driver has fallen asleep at the wheel and crashed his car into a lamp post. On the edge of the Peak District, PC Amy Hollis is on the scene of a crash where a car has come off the road and hit a bridge 60 feet above a river. The driver has been pulled out and is being treated by paramedics, but, due to the nature of the crash, Amy has to undertake a number of tests to determine whether the driver was in a fit condition to drive. Meanwhile, at a service station near the M6, PC Niaz Waddington is attempting to open up a parked vehicle where two dogs have been left with no ventilation and no water for over 45 minutes. Upon questioning the owner, Niaz discovers he has done this before and warns him of the risks of leaving pets unattended in hot vehicles. However, the discussion escalates as the owner refuses to take the advice on board.
