London, 1872. Seventeen-year-old heiress Leonora Somerville is preparing to be presented to society -- again. She's strikingly beautiful and going to be very rich, but Leo has a problem money can't solve. A curious speech disorder causes her to stutter but also allows her to imitate other people's voices flawlessly. Servants and ladies alike call her "Mad Miss Mimic" behind her back...and watch as Leo unintentionally scares off one potential husband after another.
