University student Casey Shine has her life turned upside down when she discovers she has inherited a genetic disorder from her father. This abnormality allows her to 'sleep into' other people, take over their bodies and live their lives, while the surrogate experiences a blackout. Realizing how dangerous and desirable her abilities are, Casey hunts for her father's missing research with the help of her first surrogate, FBI Negotiator Greg Shaw, hoping to find answers before the wrong people find her.
