Yana, a Gypsy artist, is led to Dr. Zastro's Sanitarium in New York City, where the emminent physician uses hypnotic powers and electrical/magnetic machinery in successfully treating his female patients.

Sparks ignite from their very first encounter. Dr. Phillipe Zostro, once engrossed in his world of science, will never be the same.
