Over the course of the treatment, Greta finds herself repeatedly sent to 1918, 1941, and back to the present. In these other worlds, Greta finds her brother alive and well --- though fearfully masking his true personality. And her former lover is now her devoted husband. But will he be unfaithful to her in this life as well?
