Several of the Collin's neighbors are victims of a series of burglaries. One evening their house is tragically hit, too: Mr. Collins finds his wife dead in the bathroom, his 16 years old daughter Aimee unconscious at the base of the stairs. She's in a coma for 18 months; when she wakes up, she can't remember anything from that fatal evening. But during her physical recovery she relives the happenings in her dreams more and more clearly. She becomes afraid that she might get a target of that murderer too.
