Despite its age, this movie shows why the "Old Mother Riley" productions were so popular. The title character is very funny in speech and movements. The theme is that someone who can be dismissed as a idiotic old woman is actually a popular woman who has the support of her down to earth daughter and friends. That those who think of the welfare of others triumph over those who are only interested in themselves.
When Mother Riley finds out that her ex-boss plans to stand for parliament and pull down her and her neighbours houses, she decides to stand against him. At first, it is taken as a joke but the villain of the movie soon realises he has to resort to underhand methods to stop her.
