SAS Rogue Heroes is returning to BBC One with a brand new series and the new outing kicks off with David Stirling (played by Connor Swindells) putting Paddy Mayne (Jack O'Connell) in charge after he was held captive.
Paddy, a born rebel, takes a different approach to leadership and his unprecedented actions keep the regiment on its toes. Creator Steven Knight teased: "Paddy is the one that punches the commanding officer, rather than being the commanding officer.
"What fascinated me all the way through reading the history was how Paddy dealt with that, and he did deal with it in an incredible and different way. I wanted Paddy front and centre, to look at his character, not brush over some of the flaws and understand – as I think with all of the men actually – that they were selected by war."
The synopsis adds: "GHQ have cast doubt over the future of the regiment, while the creation of a second unit and an influx of new arrivals make things even more difficult for the men. Can they prove that the SAS remains essential to the war, wherever it may lead them?"
Here is all you need to know about the new series.
