In 1942, a group of young women arrive in Cairo, Egypt. The Tuis, named after the beautiful New Zealand songbird, are the first women from their country to serve overseas. They are to provide respite and a touch of home to weary soldiers returning from the front line. Addy joined the Tuis for the adventure. Vivacious and outgoing, she is the life of the party, with an unforgettable voice. Margot is quiet and withdrawn, grieving the young husband she lost to the war. Despite their differences, the girls become fast friends. When the Tuis are relocated to Italy to set up clubs in grand venues, Addy and Margot are enchanted by the culture. But dark shadows loom, and when their illusion of peace is shattered by news of a devastating attack, the friends will find their endurance pushed to the limit.
