Fans of Line of Duty may be running out of time to refresh their memory about the plot on iPlayer as the brand new sixth series will be here in a few weeks.
The tense drama, created by Jed Mercurio, is about an anti-corruption police squad and it's now been two years since series five peeled back more secrets about mysterious H and the OCG.
The BBC have confirmed that series six premieres of Line of Duty on Sunday, March 21. It starts at 9pm and runs for seven weeks.
This makes sense as current Sunday night drama, Bloodlands starring James Nesbitt and also created by Jed Mercurio, ends the week before - March 14.
The first trailer for the new series, which sees Vicky McClure, Steve Arnott and Adrian Dunbar return with Kelly McDonald guest as the officer under suspicion this time, debuted during BBC One's Six Nations coverage of the Wales v England match.
Unlike series two to five, season six will have seven episodes full of AC-12 action and Mercurio has said he'd love to carry on past this new series.

He told Jay Rayner on his Out to Lunch podcast: "I really want to carry on with Line of Duty... I think that season 6 proves that there is much more ground for us still to cover."
