The play opens in the morning room of the Windermeres' residence in London. It is tea time and Lady Windermere—who is preparing for her coming of age birthday ball that evening—has a visit from a friend, Lord Darlington. She shows off her new fan: a present from her husband. She explains to Lord Darlington that she is upset over the compliments he continues to pay to her, revealing that she has very particular views about what is acceptable in society, due in part to her somewhat Puritan upbringing.
