Line of Duty's finale episode has been extended to 90 minutes to give viewers an extra half hour of action.
The final episode of season 6 is due to air on Sunday - with fans hoping the identity of H will be revealed.
The future of the show has been left hanging in the balance as Martin Compston promised: "There are a lot of pay-offs coming this Sunday. There are a lot of big answers that are coming, and I think it's deserved."
Fans of the crime drama have been waiting 10 years to find out who the mysterious fourth man is in an network of corrupt police officers.
So what can we expect from the final episode at 9pm this Sunday?
Fans are set to enjoy 90 minutes of pure action as the search continues to identify H.
There are some signs that the show is winding down with AC-12 being disbanded and Supt Ted Hastings (Adrian Dunbar), being forced into early retirement.
DI Steve Arnott (Martin Compston), risks being fired for painkiller addiction while both he and DI Kate Fleming (Vicky McClure) are suffering from PTSD due to all the violent deaths they’ve witnessed.
However, as Ted would say, Jesus, Mary and Joseph and the wee Donkey, news of the show's demise could just be a ruse.

Jo Davidson's fait is hanging in the balance as we saw her shipped off to prison after a long interrogation.
And H is still an unknown man.
There is still time for those who have not yet watched the award winning police drama to get ahead of the game before Sunday.
Buzz Bingo has crunched the numbers to see how many hours you would need to put aside ahead of this rainy weekend.
It would officially take 2,097 minutes or 34.9 hours to get fully caught up, that’s approximately 1 day & 12 hours if you wanted to watch it nonstop.
However, if you wanted a comfort break and some sleep from BBC’s exhilarating drama to get prepared for the reveal of ‘H’ in Sunday’s finale it would take roughly 2 days.
Which means with the finale premiering on Sunday at 9:00pm, you really need to start TODAY or Friday…
