Albert Perkins is blessed with a loving wife, Muriel, and cursed with a fearsome mother-in-law, Boadicea. When his friend Hilary Armitage writes to him reminiscing about the good times they used to have, Boadicea reads the letter and determines to remove her daughter instantly from the clutches of this evil sex-fiend. Albert has a hard time explaining that the letter is perfectly innocent, and anyway Hilary is a man. He isn't helped when Hilary turns up, wearing a blonde wig and a glamorous evening dress. By the time Hilary manages to explain he's come straight from doing his drag act at the local pub, it's too late - Boadicea has bashed Albert with the poker. Further disasters are in store when Hilary, anxious to make amends for the trouble he has caused, tries to help Albert.
