Winter, 1943
British Intelligence bring a new mission to the Secret Sirens Squadron, preparing them for a direct attack on the Luftwaffe.
The Mosquitos they fly can carry eight sixty-pound armour-piercing rockets on the wings. The aim is to attack the rail marshalling yards at Rouen, decimating enemy supplies.
Sisters Anna and Jennifer Nightingale, along with the rest of the Sirens, are enthusiastic about the new weapons.
But when practice begins, infighting almost leads to deadly consequences.
With the role the women are playing in the war still top secret, it is vital that any internal discord is eliminated.
Can the Nightingale sisters complete the mission? Will the Sirens master the new weapons?
Or could the enemy get one step closer to discovering their true identities…?
