A harmless piece of entertainment which puts Old Mother Riley in the center of a circus as head ringmaster. Although the big top is plagued by the disappearance of its owner, the show manages to go on. The money pours in, financial ruin is avoided, and Lucan discovers that her long-lost

daughter (McShane) is actually the star of the show. The usual padding that plagues the "Old Mother Riley" series is avoided thanks to a jolly atmosphere and some decent acts.
