Season 3 opens with the fatal shooting of a criminal suspect by an armed response unit led by Sergeant Danny Waldron (Daniel Mays).

Danny and his team claim they acted in self-defence, but AC-12, led by Superintendent Ted Hastings (Adrian Dunbar), gather evidence that suggests that this was a deliberate killing. Under interview, Danny confidently rebuts all of AC-12’s accusations that he acted unlawfully, so DC Kate Fleming (Vicky McClure) is sent undercover into Danny’s team to find out more.

Ingratiating herself to her new colleagues, Kate is quick to identify tensions and conflict between Danny and his team. But when Kate’s own conduct comes under scrutiny she finds herself sidelined from an armed drugs raid that goes very badly wrong.

DS Steve Arnott (Martin Compston, pictured) looks deeper into Danny Waldron’s background and makes a shocking discovery.

Arnott’s life is complicated by an investigation into his own past conduct, but – determined to vindicate himself – Steve prioritises his leads into the Danny Waldron case.

Undeterred by recent events, DS Steve Arnott continues to find crucial evidence in the Danny Waldron case, and when his theory is confirmed he vows to get justice.

DC Kate Fleming (Vicky McClure) discovers that PC Hari Bains (Arsher Ali) is making secret calls to an unregistered phone number while having clandestine meetings with his colleague PC Jackie Brickford (Leanne Best).

With mounting evidence, Steve (Martin Compston) approaches retired Chief Supt Patrick Fairbank to see if the allegations he’s heard were investigated during Fairbank’s time as Head Of Vice.

But Fairbank’s friendship with Supt Ted Hastings (Adrian Dunbar, pictured) stymies attempts to question the retired officer, and Steve is left suspicious of Hastings’ actions. However, with seeds of distrust sown, Hastings is starting to have his own doubts about the integrity of his former protégé Arnott.

Evidence from PC Hari Bains (Arsher Ali) leads AC-12 to believe that they are once again witnessing the work of the ‘Caddy’, a corrupt detective embedded in the force, acting as a fixer for organised crime.
