The Last of the Blonde Bombshells

After her husband's death, Elizabeth (Dame Judi Dench) decides she wants to re-kindle her musical roots. Encouraged by her granddaughter, she seeks out the almost all-female band with which she played during World War II. The one non-female in the troop was a cross-dressing drummer with whom she still is friends. With his help, they start tracking down their old cronies, and find some dead and some mentally incompetent. Slowly the band grows, but their sound is lacking. When the singer is added to the mix, everything comes together.
