Telly Paretta is tormented by the memory of her eight-year-old son Sam's death in a plane crash 14 months ago. While trying to work through her grief, and her subsequent estrangement from her husband Jim, she is informed by her psychiatrist, Dr. Munce, that she is suffering from delusions, that her son never existed and she is fabricating his memories. Stunned, she tries to find evidence of Sam's existence. But it has all disappeared. Telly is convinced she is going mad until she meets Ash Correll, the father of one of the other plane crash victims. Together, they embark on a search to prove the existence of their children and reclaim their sanity.
