When Jinx Kingsley, respected fashion photographer and only daughter of millionaire Adam Kingsley, is found unconscious in the wreckage of a mysterious car accident on an abandoned airfield, the police suspect a suicide attempt. Blood samples taken at the scene reveal an alarmingly high blood-alcohol level, and authorities discover that just one day prior to the accident, neighbors found an unconscious Jinx parked in her garage with the car engine running.

Matters are further complicated when it is learned that Jinx's fiance has run away with her best friend, and neither can be located for questioning.

Dazed, confused, and suffering from post-traumatic amnesia, Jinx is placed in an exclusive private clinic, where she struggles to regain her memory with the help of Dr. Alan Protheroe. As their professional relationship grows and the dialogue between them deepens, Protheroe starts to see Jinx as the woman she really is: brilliant, strong-willed, and by her own admission far too proud to kill herself. At first, Jinx can remember nothing about her alleged suicide attempt.

But with Protheroe's help, memories begin to surface - memories of desperation and absolute terror.
