London's police force is in need of a public image revamp. And Chief Constable Richard Miller has found just the woman to do it...American visionary from the world of new media Liz Garvey, sets out to revolutionise the force's PR department just as an outbreak of violence erupts.
The TSG is dispatched to a riot held by the Youth Offenders Institution. Vas hopes for a last quiet day in the field before firearms training. Coward may have noticed dangerous communications within the ranks. Footage of Collister's shooting is released, involving an unarmed suspect, leaving Collister with anxiety. Due to the footage, Collister's colleagues Forbes and Banjo think of a plan to relieve his anxiety. Meanwhile, a PR plan direct from Scotland Yard hits turmoil, tensions arise between Miller and Deputy Mayor Grant Delgado.
Director of Communications Liz Garvey introduces her creation of 'Metwork', a new news channel for force use and her PR/Communication department. Garvey continues to receive backlash from her deputy, Finn Kirkwood, who is determined to stop the 'Metwork' from going ahead. Meanwhile, Collister's mental state is desperately deteriorating whilst on duty, and Vas plans to improve his attitude towards the job in hand.
Miller is asked to oversee an operation into a possible bomb threat on a Money expo at the Thameside centre, but continuing personal problems begin to cloud his judgement. A robot is sent in to inspect a suspicious package left in a coffee bar; the package is deemed harmless. However, minutes after leaving the scene, a bomb explodes, resulting in casualties.
The search for the Thameside bomber is underway, while the fallout from Miller's death is felt throughout the department. Kirkwood seizes his chance to try and extradite Garvey, while Inglis shines in a moment of glory having been made acting commissioner. Clarkey and Davina Bancroft's personal life gets in the way during the search and they fail to search the house where the bomber lives. Luckily, Asst Commissioner Sharon Franklin is able to defuse the situation, which gives Garvey an idea.
The aftermath of the teen shooting sees Banjo, Forbes, Collister and Vas being interviewed by an inquest panel over their involvement, and it's not long before Banjo is forced to dish on Collister's recent troubles. A troubled Vas admits to Coward that he faked the crime scene by placing the gun in the boy's hand, unaware that he has been recorded. Kirkwood continues to make things difficult for Garvey, but when a search for a missing boy gets underway, the latter uses the opportunity to highlight Franklin's adept qualities at making commissioner, fully aware that Franklin being appointed commissioner would simultaneously get Kirkwood off her back and eliminate Inglis.
Footage of Banjo trashing a wheelie bin goes viral. Franklin's proposals of turning PCSO's into actual police officers results in unauthorised strike action across the two police units. Vas, Forbes and Banjo perform an off-the-record raid on Coward's flat to retrieve the evidence of Vas' confession, but Forbes has a crisis of conscience and offers the footage up to Garvey. Word spreads of the TSG and ARV's unsanctioned strike action, resulting in widespread rioting and looting across London. Meanwhile, when talks leak of Franklin's policy for 'cops to arrest cops' leaks out, Garvey decides it's time to back a new horse and pulls out all of the strings for Inglis' bid for commissioner.
