Lady Hadwell, the widow of an aristocrat is struggling to make ends meet by opening her home to the public. The youngest of her three daughters, Charlotte, known as "Charlie", is a tomboy. Their loyal assistant, Joe, is in love with Charlie. When he learns he has won a fortune on the football pools, he conceals the fact from his employers. In the meantime, her mother is hoping for an engagement between Charlie and an American millionaire. The most memorable moment of the show is when Charlie has to return her hired evening gown, and the rest of the guests at the ball also decide to cavort in their underwear.
