The play follows Eliza Doolittle, a Cockney flower girl, who takes speech lessons from phonetics professor Henry Higgins. Higgins bets that he can make Eliza pass as a lady by teaching her to speak properly. He is successful and Eliza dazzles guests at an ambassador's party. However, Eliza then questions her identity and purpose now that the bet is won. She argues with Higgins, feeling used, before ultimately standing up for her own independence and dignity.
