In the late 19th‑century world of mesmerism, a striking young aristocrat arrives at a St. Louis doctor's office, seeking more than a simple demonstration. She asks Dr. Herbert Flint to split her mind, giving her a brief, carefree alter‑ego that can escape the grief that haunts her. Intrigued, the hypnotist agrees, and a single session produces a startlingly vivid transformation—her demeanor, expression, even her bearing shift to that of a haughty, flamboyant socialite.
As the weeks pass, the woman returns, yearning for the same exhilarating escape, and each hypnotic experiment deepens the mystery of what lies behind her dual selves. Observers begin to wonder whether the changes are merely suggestion or something more unsettling, especially when she unexpectedly appears in public embodying the very persona she once conjured under trance. The story follows the delicate balance between scientific curiosity and the uncanny consequences of playing with the mind.
