Line of Duty fanatics (that's pretty much of all us), we've got some good news for you.
The trailer (which you can watch below) of the sixth season of Jed Mercurio's widely acclaimed police corruption drama has been released and sees AC-12 handle a brand new case, where they investigate the unsolved murder of senior police officer Gail Vella (played by Andi Osho) in their highest-profile case to date.
Of course, those on the force have to discover whether police corruption, or 'bent coppers' as they are more commonly referred to, contributed to the circumstances that led to Gail's death remaining unsolved.
Supt Ted Hastings (Adrian Dunbar), DI Kate Fleming (Vicky McClure) and DS Steve Arnott (Martin Compston) are now required to investigate DCI Joanne Davidson, "the senior investigating officer of an unsolved murder, whose unconventional conduct raises suspicions at AC-12."
Joanne is played by Kelly Macdonald, who has starred in Trainspotting, Black Mirror and Boardwalk Empire.
And judging by her icy cold demeanour, she could be their toughest and most slippery adversary yet - with the tension of the high-risk case clearly getting to the rest of AC-12 as seen in the first look.
The trailer also shows the arrival of AC-12 newbie DC Chloe Bishop, played by Shalom Brune-Franklin. She looks set to help Kate and Steve in uncovering the identity of the mysterious 'H', the shadowy figure who is part of a ring of senior officers that helped cover up a child sex-trafficking ring.
While very little is known about the new series of Line of Duty, Martin Compston, who plays Steve Arnott in the show, has teased there is a "bombshell" twist midway through the series.
"For this year, I think we've filmed [episodes] one and two, and as a cast, we've got [the scripts for] three and four, and Jed is writing five and six and we haven't seen them, and there's a bombshell at the end of four and I'm desperate to find out what happens," he told RadioTimes.com.
"We're just the same as everybody else and as far as H goes, as soon as we find him we're out a job!"
Line Of Duty returns Sunday 21st March at 9pm on BBC One.
