The BBC drama is coming back!
Almost a year after its explosive series three finale Line of Duty is making a long-awaited return to our screens.
The fast paced anti-corruption police drama has a new channel and some new faces but viewers will be glad to know the main cast are all coming back for the new episodes.
Here’s everything we know so far…
When does Line of Duty series 4 start?
The new series of Line of Duty will start on Sunday 26 March at 9pm.
What channel is Line of Duty on?
After three series’ on BBC Two, Line of Duty is moving to BBC One.
Who is returning?
The AC-12 gang is still in one piece (just). Superintendent Ted Hastings, played by Adrian Dunbar, Martin Compston’s DS Steve Arnott and DS Kate Flemming, portrayed by Vicky McClure are back to back to fight corruption in the force.
Who are the new characters?
Thandie Newton joins as DCI Roz Huntley and AC-12 gets an injection of guy candy in the form of Our Girl star Royce Pierreson, who plays DC Jamie Desford.
How did Line of Duty series 3 end?
If you’re in need of a little recap, the last series saw Arnott and Flemming finally learn the true identity of the Caddy – DI Matthew ‘Dot’ Cotton.
As viewers will remember, the Caddy had been leaking information from inside the police force and Dot had already made his way up the ranks in AC-12 before being rumbled.
Dot tried to escape justice but, in a twist of fate, ended up taking two bullets to save Kate’s life. He used his dying breaths to deliver a witness statement to Kate but, before you start feeling sorry for him, remember he did shoot DI Lindsay Denton…
What’s Line of Duty series 4 about?
Ted, Steve and Kate are assigned to investigate DCI Huntley, who is running Operation Trapdoor. It’s not yet known whether Thandie’s character is corrupt but one thing’s for sure: you can expect some brilliantly nail-biting drama from the six six-hour episodes…
