This episode focuses on the issue of irresponsible driving, particularly when combined with the use of mobile phones at the wheel. He goes out on patrol with a specialist police team who tackle what they call the ‘Fatal Five' - speeding, driving without a seatbelt, driving while distracted, careless driving, and being behind the wheel under the influence of drugs or drink. And he meets a man who openly admits to having driven under the influence of hard drugs.

Jeremy investigates how dogs bred to attack are being used by gangs as weapons and by individuals as status symbols. He meets members of the Met Police's status dogs unit, and speaks to gang members who tell him how they train the canines to be more aggressive.

He also speaks to a pitbull fan who believes the banned dog has been given a bad press, meets a dog trainer who says with the right training any pooch can be tamed, and is set upon by a trained attack dog to gain an insight into the experience.
