It’s the show that goes where others are too afraid to venture. Series 1 saw Lacey Turner (EastEnders) star as Molly, a combat medical technician in Afghanistan. In series 2, Michelle Keegan (Coronation Street) took on the lead role as Georgie, another army medic. We followed her on duty in Kenya, and her on-off love story with Elvis (Luke Pasqualino, The Musketeers).

Series 3 is made up of three mini-series. The first, which aired at the end of last year, saw Georgie on a humanitarian mission in Nepal, which ended in personal disaster. (Spoiler alert – Elvis has left the building.)

This brand new second instalment takes us to Nigeria, where violent jihadist militant organisation Boko Haram has established strongholds in the northern part of the country. According to Our Girl creator, Tony Grounds, the storyline was influenced by the real-life abduction of 276 Chibok schoolgirls by the terrorist group in 2014.

The third part of the mini-series involves a mission on the Belize/Guatemala border. So, it’s fair to say that the cast and crew have packed a lot in. And, having seen a sneak peek of what’s to come, it’s clear that their hard work has paid off. We catch up with Keegan to get the inside scoop…
