Victorian England, 1880. Mortimer Granville, a young doctor disillusioned by his colleagues’ medieval practices, starts working for Dr Dalrymple, who treats women’s Hysteria by offering them intimate manual relief… Demand becomes so great that Mortimer just cannot keep up with it. With the help of his friend Edmund, a millionaire dandy with a passion for electricity, they invent the world’s first vibrator, which proves to be an extraordinary success. Along the way, Mortimer falls in love with Charlotte, Dalrymple’s beautiful, and most unconventional daughter.
