What if you were told that every moment you experienced and every memory you held dear never happened?

Nine year old Sam Paretta is dead, killed in a plane crash. Even though it's been fourteen months since the accident, his mother, Telly (Julianne Moore, Far From Heaven), still grieves over the loss. But suddenly, her husband (Anthony Edwards, "ER") swears they never had a child and her psychiatrist (Gary Sinise, "C.S.I.:NY") insists she's delusional. But worst of all, there is absolutely no evidence to prove Sam ever existed. Haunted by the memories of her son, Telly's search for the truth propels her into a dark mind-shattering conspiracy of unearthly terror.
