Although she lives in the White House, Mimi Mouse accidentally gets packed in the First Lady’s suitcase and travels across the Atlantic Ocean on Air Force One. When the plane lands, she discovers that she is in London for a visit with the Queen of England, along with the First Family. While there, she enjoys a cup of tea and scones. She finds out that cookies can taste very differently away from the White House. The Queen is lovely and well mannered, but Mimi Mouse loves her beautiful crown of jewels the most. After a week of sightseeing, Mimi Mouse returns to the White House where her friends make her a special crown to wear too. She decides that although England is a nice place to visit, there is no place like her little home in the wall at the White House.
