 After her husband s death, a widow (Judy Dench) decides she wants to re-kindle her musical roots. Encouraged by her grand-daughter, she seeks out the almost all-female band she played with during World War II. The one non-female in the troop was a cross-dressing drummer (Ian Holm) 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 (Cleo Laine) is added to the mix, everything comes together.
