Mrs Abbott is flustered at the thought of putting up a lady from the Red Cross, but is happily surprised when she turns out to be an old friend from her previous life as Miss Buncle, infamous writer. Of course, she's now far too busy with her children to write, not to mention helping out in the lives of the villagers. And with a possible spy in their midst, evacuated families, potential love matches and a visit from a famous writer, she's got her work cut out for her. Luckily for her, the other Mrs Abbott is around to help.
