Cyma Roget, a beautiful young woman, has fallen under the influence of the evil Hindu scientist Chandra Dak, who can cast her at will into a hypnotic state resembling death. Chandra Dak's power over Cyma wanes as his love for her grows, however, and one night she escapes and takes refuge in the atelier of three young and struggling Bohemian artists. During her stay at the atelier, she becomes an artist's model and forms an attachment to one of the artists, Paul Bridere, but soon Chandra Dak falls out of love with Cyma and sends her into a hypnotic coma. To all appearances dead, Cyma is interred in a vault, but Chandra Dak's death ends her coma, and she is rescued from the vault and restored to the arms of Paul.
