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.

Following Brexit, and with the news that levels of hate crime were on the rise even before June 2016, Jeremy investigates how tensions between different groups are simmering. The programme visits Bolton to witness a demonstration against plans for a new mosque, and Jeremy attends a mediation meeting between the two sides aimed at reaching an amicable resolution. He also looks at a rise in homophobic attacks, joining revellers at Pride Manchester, and meeting a participant who has been physically abused because of his sexuality. The programme also features a social experiment to find out who might intervene when a waitress starts abusing a gay couple.
