The artist Mrs E. MacAvity is seen painting a portrait of the Prince of Wales (?)
Mrs E. MacAvity - an artist from Nova Scotia - is given special sittings at St. James' Palace to paint a portrait of the Prince of Wales.
We see the artist in her studio (or possibly a set) with the portrait applying some finishing touches. She looks directly at the camera as if we are her subject. She then gives "her girlie" a mouse (for no apparent reason!). C/U of girl (her daughter presumably) holding a mouse. Mother drinks a cup of tea and watches as the mouse crawls over her daughter's hands.
