1942, and singing group the Bluebird Girls have swapped the theatres of southern England for army tents in the Libyan desert.

Their mission is to boost the morale of the brave British troops fighting under the hot sun, where there is no end yet in sight to the war. Bea, Rainey, and Ivy must shake off the toll the war has taken on their friends, loved ones and homes if they are to keep their own spirits up while performing so far from home.

With a smile on their faces and a song in their hearts, the Bluebird Girls will keep fighting on until the very end.
