What happens when a young woman is dispatched to an Army base in Afghanistan, swiftly becoming the target of insurgent bullets? And what happens when everything she thought she knew about herself is tested thousands of miles from home? "Our Girl" finds Molly Dawes (Lacey Turner) leaving the world she knew behind her and taking on the challenge of serving as an army medic in Afghanistan. Thrilled to find herself out of the ordinary and on the front line, she gets off to a bad start with her platoon leader Captain James (Ben Aldridge) and discovers that she's serving in the company of 'Smurf' (Iwan Rheon), a face from the past she'd rather forget. One heroic act that saves a life while risking her own brings a new level of respect from her comrades. But Molly is about to learn that not everything is as it seems and that every opportunity presents the kind of challenge that comes with a price - a price that can end up costing lives.
