It is Guy Fawkes Night at the Farnaby manor and time for the traditional bonfire. Miss Farnaby supports the bonfire but normally does not participate or if she does, she does so from a distance. Well now, Mulberry is determined to end this non-participation by his employer, and sets out to make the night one to remember, with fireworks included in the evenings festivities. As usual, Bert and Alice think that they should not have to do everything by themselves and fully expected Mulberry to assist them, which of course he doesn't, much to their dismay. (thetvdb.com)
