Don't let her small stature fool you. Standing at under five feet tall, Dr. Ruth Westheimer is a force. A pioneer in the field of sex therapy, she became a household name in the '80s and '90s. At 90 years old, she hasn't stopped working—and still promises the best sex you've ever had if you listen to her. Filmmaker Ryan White captures Dr. Ruth's exuberant and snappy personality as she hopscotches from speaking engagements to TV and radio appearances. Alongside her optimism, however, are storybook-like animations that bring Dr. Ruth's childhood as an orphan of the Holocaust to life. The film is an inspiring and entertaining portrait of a trailblazer that reveals the darkness Dr. Ruth emerged from to bring light to so many people.
