The Wrens Wartime Christmas

German U-boats are getting through the defences. It's up to the Wrens to stop them.

After her fianc died in the sinking of the Royal Oak, Mary finds herself stationed in Orkney, still battling her grief. With Iris and Sally by her side, she is gradually overcoming her loss and is surprised to be helped by the irascible Joe.

Joe is a signalman aboard the Kelpie and his cheeky Morse code signals to Mary while she's on shift bring her cheer and exasperation in equal measure. With Christmas round the corner, Mary is opening herself back up to the festive spirit and to love.
