Unlike the first and second, series three will be spilt up into 12 episodes and divided into three missions, with the first being shown later this year.

Keegan plays army medic Corporal Georgie Lane, who has previously completed a number of tours in Afghanistan. The start of series three sees her on a relief mission in Nepal following an earthquake, which has had hazardous and unpredictable consequences for the community.

Also returning for this series are Luke Pasqualino (Skins) as Special Forces officer Elvis Harte, Ben Aldridge (Fleabag) as Captain James and Sean Sagar (Top Boy) as Monk.

Keegan said: “I’m so happy to be shooting the new series of Our Girl out in Nepal and so very excited to bring more stories of Georgie Lane to life. It’s an amazing experience to be working on such important stories with such an incredible group of people.”

Writer and creator Tony Grounds added: “Michelle Keegan, brilliantly reprising her role as Corporal Georgie Lane, shows remarkable courage in the face of adversity and inspires the troops to perform their duty with bravery and compassion."

More information on the later two missions of series three will be released in due course.
