BBC is bringing back war drama Our Girl, starring Michelle Keegan, for a fourth season.

The drama, which is produced by BBC Studios, is returning to BBC One for a six-part series. Keegan stars as Georgie Lane and takes place one year on from her last tour in Bangladesh.

Having been promoted to Sergeant, and now training a new bunch of medics, Lane is living back in Manchester with her family, and insistent that she’s not joining 2 Section’s upcoming deployment to Afghanistan. However, when a night on the town results in a near-fatal incident, she needs to face her own fears and return to Afghanistan after losing the love of her life, Elvis, to a Taliban attack.

Written and created by Tony Grounds, the show will film in April in South Africa. Produced by Yvonne Francas and exec produced by Grounds, Roberto Troni, Hilary Salmon for BBC Studios and Mona Qureshi for BBC One.

Keegan said, “Being in Our Girl has been one of the highlights of my career so far. I feel very lucky to be part of the show and I’m really excited that it’s coming back. The audience response has been so positive and I think Georgie is a character who resonates with viewers. I absolutely love playing the role. Be prepared for another incredible series – Georgie’s still got unfinished business.”

Grounds said, “I’m absolutely delighted that Michelle Keegan will be reprising her role as Georgie Lane for another tour of Our Girl. 2 Section are deployed to Afghanistan as part of Nato’s Resolute Support Mission to develop the military capability of the Afghanistan government’s armed forces. But with the Taliban controlling large swathes of the country and Georgie Lane’s haunting memories of Elvis lost last time she was in the country, this mission was never going to be easy.”

Hilary Salmon, Executive Producer for BBC Studios, added, “The new series of Our Girl is an opportunity for us to see Georgie in a new stage of her life, as she comes to terms with life without Elvis and reassesses her relationship to the army and the emotional toll it has taken. We are thrilled that Michelle Keegan will once again star in this new six-part story that is both exciting and moving and contains unexpected twists.”
