Based on a true story, this hilarious and heart-warming comedy invites us into the world of Florence Foster Jenkins (1868-1944), widely acknowledged as the worst singer in the world, yet who became the must-see artist in New York in the early 1940s. Spinning from charity recitals before groups of devoted friends to extravagant balls, Florence's enthusiasm and joy more than made up for her imperfect pitch and she culminated her unconventional career as the “First Lady of the Sliding Scale” in a triumphant sell-out concert at Carnegie Hall, New York.
